Lookin' good Mrs. Goop!

Gwyneth Paltrow attended a performance of mom Blythe Danner's play, The Country House, on Broadway on Thursday night, and the Oscar winner was beaming when she left. Or maybe she was just surprised with the amount of attention she received?

After her split from husband Chris Martin earlier this year, Gwyn's been all over the news, and after he rebounded with 24-year-old Jennifer Lawrence, that didn't exactly help. Of course, when J. Law had her nude photo scandal, that only added fuel to the fire, and according to some reports, Gwynnie approves of Jen, but according to others, she won't even let Chris mention Jen to the former couple's kids!

"Gwyneth is doing everything possible to make sure [Jen] isn’t mentioned in front of Apple and Moses,” a source told Radar. "She doesn’t want them upset by Chris’ 'younger lady friend,' which is how Gwyneth refers to Jen. Explicitly instructed by Gwyneth, Chris has been told not to discuss his girlfriend in front of the kids.”

"Gwyneth has told Chris she absolutely does not want any of Jen’s personal items left behind at Chris’ house, that the kids might come across," the source added. Yikes!

Ashton Kutcher and Mila Kunis welcomed a baby girl on Tuesday night, and on Thursday evening Ashton took to his website to reveal her name.

Ashton wrote:

"Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy."

The former Punk'd host added, "Can you guess which one is ours, or does it really matter? All babies are cute," and posted 8 photos: 6 of human babies, one of a goat and one of a dog. We wouldn't be surprised if NONE of the photos are of little miss Wyatt, but two of the tiny tikes look like they could belong to Mila and Ashton.

Check out the gallery below and let us know which baby you think could be theirs!

Justin Bieber partied at The Arc nightclub in Paris on Thursday night, and when it was time to head home, the 20-year-old pop star took this colorfully-dressed brunette lady with him!

Bieber hopped into his chauffeured car first while his mystery chick smoked a cigarette and made faces at photographers, and she eventually got in with him and the two headed back to his hotel.

First he stepped out with Kendall Jenner and now he's back to hooking up with randoms? Poor Selena Gomez! We thought everything was going well with Jelena after their romantic Caribbean vacation last week!

But apparently the hot/cold couple have split yet again, as Selena flew home from France alone on Wednesday, unfollowed the Biebs on Instagram and posted a very cryptic tweet. "Sometimes we think we aren't good enough," she wrote. "But then I realize when I think I'm alone I have God."

So ... How long before Biebs is back with SG again? You know it's never over!

Well, it's no Batmobile but close!

Yesterday, Ben Affleck looked like a billion bucks as he and his Tesla arrived to Soho House in Beverly Hills to grab a bite to eat.

The 42-year-old Oscar winner's Batman body has been on full display already but wife Jennifer Garner gave a more in-depth take on his transformation.

"He has put on 30 pounds of muscle and he's 8 percent body fat," she revealed. "He looks pretty good!" Garner said while on the set of Live with Kelly & Michael. "It's a little bit like 'Whoa, who are you?,'" the 42-year-old actress continued, jokingly. "It feels like I'm having an affair. But I don't mind, I'm not complaining."

She's already a fan!

Ellen Pompeo and husband Chris Ivery have welcomed their second daughter while staying relatively under the radar with the announcement.

"Sienna May Ivery welcome to the world," Pompeo posted to Instagram on Thursday. "We love you more than words can say." The caption came along with a precious picture of the baby girl.

"Sienna was born via surrogate & I would like to thank my whole @ShondalandTV family for helping us enjoy these first few weeks privately," Pompeo added via Twitter.

The 44-year-old Grey's Anatomy actress and her music producer hubby kept the baby news a secret from those outside of their circle, much like their New York City wedding back in November 2007. That time, the couple exchanged vows at City Hall in Lower Manhattan where Mayor Michael Bloomberg acted as their witness.

She just keeps on looking better and better!

It was just another day for Jennifer Lopez, who looked extremely stunning in not an array of sexy outfits while on set on American Idol in Los Angeles on Thursday. Guess Diddy's comments were spot on!

The 45-year-old entertainer's mogul ex, who she still calls Puff recently gushed about Lopez's figure while watching her Booty music video.

“Oh my God, oh my God! I am so lucky to have that great woman in my history,” Diddy said. “[Her booty] is great. It’s a work of art. It’s something that will go down in history. Also her talent, her drive, her determination.” What a ringing endorsement!

He also added that Kim Kardashian couldn't hold a candle to Lopez's derriere! Her response? Classic J.Lo.

"As much as he roots for me and as proud as he is of me and of the time we had together, I, I am just as proud to see what he's done," the Idol judge said in an interview. "Seeing him involved in Revolt and all the things that he's done as a business man and still being so true to his music and his art trying to uplift his community in his own way, and it's the same thing that I try to do and I feel like I learned a lot from him coming up, watching him."

Sounds like there's a lot of love there!

If she's upset, she's not showing it!

Kristen Stewart went for a drive around L.A. this morning with her pal CJ, and he was grinning from ear to ear as he sat in the passenger seat of her ride. Now that Robert Pattinson has moved full steam ahead with new girlfriend FKA Twigs, let's hope she's not still carrying a torch for her former love.

The Twilight star has been back and forth from Japan while she films her upcoming movie Equals, so it's not like she's ever in one place long enough to strike up a romance. Then again, there are rumors she is secretly dating co-star Nicholas Hoult, so maybe she's mixing business with pleasure.

Eat your heart out R-Patz!

While Kendall Jenner is taking Paris by storm, modeling for Balmain and Chanel, sister Kylie Jenner is posing too ... in her mom's backyard. Looks like The Most Forgotten About Kardashian is trying to get some much-needed attention!

No matter how much attention Kylie tries to get with constant barrage of sexed-up swim pics, the 16-year-old just isn't going to be able to steal her sister's thunder.

We'd really love it if Kris Jenner was around to tell her teenaged daughter to put some clothes on -- but we are understand that Kris is busy ... DOING ANYTHING ELSE!

We aren't sure exactly why Kylie thought a pic of herself getting up close and personal with a column would be a good idea, but then again, we're of the thought that going to high school instead of going to the Calabasas mall is probably a good idea too! Guess we aren't really sure we are on the same decision-making page as ole Kylie. Oh well!
