Ellen DeGeneres plans to wed longtime girlfriend Portia de Rossi, she announced during a taping of her show Thursday.

In the episode, airing Friday (the news was first reported by TMZ), DeGeneres revealed the big news and told the crowd, “I’m very excited.” The announcement immediately followed the news that California’s Supreme Court struck down a law banning gay marriage.

De Rossi, 35, was reportedly in the studio when DeGeneres – who just celebrated her 50th birthday – broke the news.

In what’s sure to be a controversial decision, the California’s Supreme Court ruled that people have a fundamental “right to marry” the partner of their choosing – therefore the previous ban on gay marriage was ruled unconstitutional.

The two stars began dating in December 2004, as de Rossi was appearing on the FOX sitcom Arrested Development.

One key to their happiness, DeGeneres said last year, is that they learn from one another. “She’s taught me lessons about myself, and I feel like I’ve taught her,” said the TV host. “We’ve both changed and grown, and we just feel like, ‘Oh, okay, this is completion.’ “

Ashlee Simpson and Pete Wentz were married Saturday evening in an intimate ceremony, their spokesperson tells PEOPLE exclusively.

“We’re delighted to confirm that Pete Wentz and Ashlee Simpson were married this evening in front of family and close friends,” said the spokesperson.

Simpson, 23, wore an ivory lace wedding gown by Monique Lhuillier and jewels by William Noble as she and Wentz, 28, exchanged vows in front of 150 guests at her parents’ Los Angeles area home.

Dad Joe Simpson performed the non-denominational ceremony, while sister Jessica served as maid of honor. Wentz’s English bulldog, Hemingway, was the ring-bearer. Guests included Jessica’s boyfriend, Dallas Cowboys quarterback Tony Romo, Nicole Richie and Joel Madden, as well as actor Donald Faison with girlfriend CaCee Cobb.

Simpson told PEOPLE on Friday that she was never the type to dream about her wedding when she was growing up, but changed her tune once she got engaged. “Now that I’m doing it, I definitely have that big dream. It kind of went more fairytale than I thought. I got really into it.” Added Wentz, “She has this amazing imagination and to watch it take place is an awesome thing.”

With the help of wedding planner Mindy Weiss, Simpson got her dream nuptials: The Alice in Wonderland themed reception featured a wedding cake by Sam Godfrey of Perfect Endings with a top hat, tea pot, stop watch and a pot of flowers on top. The elaborate centerpieces of black beauty roses were by Mark’s Garden. Guests were served Rose Veuve Clicquot champagne followed by a sit-down dinner and dancing to a deejay.

Simpson, who sources say is pregnant with the couple’s first child, and Wentz, the bassist for Fall Out Boy, have been linked since the fall of 2006, when they were spotted kissing at a New York nightclub. They announced their engagement last month.

“He’s a cutie,” Simpson told PEOPLE last year. “He has an awesome personality and kind of brings out the best of me and I knew that even before we were dating. There was just like an awesome connection we had.”

After they’d been dating almost a year, Wentz told PEOPLE, “We’re past the honeymoon period. The truth is, it’s crazy to be able to kiss your best friend. It’s just a really awesome thing.”

This is the first marriage for both.

Britney Spears returned to CBS’s How I Met Your Mother Monday as Abby, the silly-vulnerable receptionist with an unrequited crush on Ted (Josh Radnor). The ratings spiked with her first appearance, so she was quickly shoehorned into this new episode.

The fact that Britney’s second guest spot really didn’t work was no fault of hers. She’s not at all bad at playing clunkily-sweetly dumb. I liked the way she tried to vent her conflicted feelings of anger and love for Ted while lying in bed and staring dreamily at the ceiling: “You know what I hate most about Ted? His stupid hair … His stupid, lame, awesome hair. It’s so stupid and awesome,” she said with a cute, singsong lilt.

But the script was an awful piece of specialty construction. Abby’s reverie occurred in a bed shared with Barney (Neil Patrick Harris), who was also feeling rejected by Ted — as a friend. His and Abby’s mutual annoyance turned them both on, so they slept together.

Then they decided to pose as a couple to annoy Ted. Then Barney carried the joke too far by proposing to Abby. Then Abby suddenly thought Barney really loved her. Then, to get out of the engagement, Barney told Abby that their romance had done the trick and now a jealous Ted did love Abby. And then Abby got this crazy love-hungry Shelley Winters-like gleam in her eye, setting up the possibility for a third guest spot.

Well, that’s a lot to cram into the subplot of a 20-odd-minute show. It would have taken me less time to type out the synopsis of Dangerous Liaisons. The twists felt arbitrary and perverse, even for a so-so sitcom, which is what HIMYM is.

It’s time for Britney to move on to her next cameo project. Ugly Betty would have been a good fit, but Lindsay Lohan is already there. –Tom Gliatto

Rumor has it that Ashlee Simpson and Pete Wentz are getting married this Saturday. Nothing like an “unexpected” (you know Ashlee tricked Pete) pregnancy to make a wedding happen in Hollywood. The guests don’t know where the wedding is at yet, but they’ve received save the dates and they know they will be privately transported to the wedding site.

Umm, who the hell do these two think they are? Are they even big enough celebrities to pull this secret location shit? And does anyone care enough to tell the press? Hell, if I was invited I wouldn’t even go because the chances are pretty good that one of those two doofus’s is going to sing at the wedding. Yuck. Plus, Jessica Simpson will be there carrying around her mangy dog Daisy and wearing stupid hair extensions just generally being dumb. I wonder if they’ll invite Nick Lachey? Then I’d go. Just to see the drunk-wedding dram unfold.

Motherhood must really be taking its toll on old J.Lo because she looks used and abused. She always wore about 12 lbs of make-up, so that’s not new, but it looks more cakey and disgusting now. And she just seems like she’s really faking to act semi-happy. I don’t know, she just looks like shit here and, well, lately.

I bet she has a bunch of nannies who are “taking care of” (aka raising) her twins. Do you guys think she and Marc Anthony are being real, normal parents or do you think they are being typical celebrities?

Jenna Bush, the daughter of the President, got married over the weekend. I would put who to, where at, and all that, but it’s all over the news and I know you really don’t care. Just look at the pictures–they’re far more interesting.

I like Jenna Bush because she is such a fake! She is so much of a fake that you have to like her. She’s past the fakeness that you hate and on to the fakeness that you just have to love. Remember when she used to get drunk all the time, fall down in public, and change her underwear for the world to see? Oh you know she is still that girl, only tamed. I don’t believe for one second she isn’t still that girl! That is why I love her. Cause I know she’s still that skeeze she used to be. It’s only a matter of time before the old Jenna Bush reappears!

Jamie Lynn Spears is doing so much better with her pregnancy than Britney did with either of her two pregnancies. I mean, she’s actually taking showers and getting dressed up! Britney always looked like her hair hadn’t been washed since the baby was conceived and she dressed like crap, too. But here’s Jamie Lynn, all dressed up and looking cute (I could live without the glasses), getting gas and running errands. She should be careful in those heels but still, she looks good. Props to her.

Who knows if John Mayer and Jennifer Aniston are really dating. We’ve seen pictures of them together, including this newest one of the two of them cuddling in at Mandarin Oriental in Miami, but what does that prove? John Mayer goes through chicks like Amy Winehouse goes through a ten-sack. I just want Jennifer to find someone and get gobs of press attention. I want her to overshadow Angie because, really, aren’t we all getting tired of Angie? I am.

Amy Winehouse has been skinny the last couple of years. I mean, we all know it’s due to her addiction to drugs but lately I’ve been looking at pictures of her wondering if she doesn’t have an eating disorder or something, too? Her body is all sunken in and her bones are sticking out. She seriously is so messed up. I don’t get why someone doesn’t just grab a hold of her and say “you have to clean your act up or you are going to die.” Yuck.

And what’s with her running barefoot and topless throughout the woods? That’s screaming “I’m on a ferocious drug trip” yet there are never any police around to question her. She is going to kill herself with drugs and then people are going to look back and have a lot of regrets. Sadly this is true!
