Jennifer Aniston and Justin Theroux attended the New York City premiere of her upcoming film, Cake, at Tribeca Grand Hotel, and after hitting the red carpet, the monochromatic duo went to an after party at Jimmy's.

Jen wore a sexy plaid dress, tights and knee boots while her fiance went with his usual all-black ensemble. And despite the fact that Jen's engagement ring was off a few weeks ago, she was all smiles and happily showed it off earlier in the day when she left her hotel.

But seeing as these two have been engaged for over two years, isn't it time they walk down the aisle? Perhaps the former Friends star and her screenwriter/actor beau are planning a winter wedding?

Her Goop Holiday Gift Guide was slightly over-the-top, but this outfit is just ridiculous!

On Saturday afternoon Gwyneth Paltrow went shopping with her two children Apple, 10, and Moses, 8, at the Brentwood Country Mart, and while she looked every bit the sexy soccer mom from the knees up, her $1080 Stella McCartney star flatform sneakers look like something that belong in a Spice Girl music video.

Gwyneth's shorts may not be inappropriately short and her legs do look amazing, but we definitely got a peek at some cellulite dimples on the 42-year-old Oscar winner's upper thigh. See! She is human after all!

Madonna posted these snapshots of her children Lourdes, 18, and Rocco, 14, but they're not so little anymore -- in fact, they're practically ready to move out of the house!

The Material Girl captioned the pics, "Kidzzzzzzzzz #livingforlove" and "Ra ga ga ga za za 2littlrfarts." While her "kidz" might have more mature captions on their own social media accounts, it's clear that the queen of pop just loves spending time with them!

Lourdes is currently attending the University Of Michigan, so Madge be thrilled to have her back for Thanksgiving break. Rocco didn't seem super stoked about posing for photos, but this morning he posted a selfie with his big sis, so clearly he's enjoying catching up with her as well.

But where were M's daughter Mercy and son David?

This is just high-larious! But it would have been even better if they recreated the over-the-top music video for the tune as well...

Last night Woody Harrelson appeared on Saturday Night Live, and for his opening monologue he was handed a guitar and promptly starting singing about the year 1989. As you may know, 1989 was the first time he hosted SNL (and he was baked out of his mind), and seeing as Taylor Swift's new album is called 1989, someone had the genius idea of Woody telling his version of what happened to the tune of Taylor Swift's new hit, "Blank Space."

But the real treat was a few minutes into the song when Woody was joined by his Mockingjay co-stars Josh Hutcherson, Liam Hemsworth, and Jennifer Lawrence. Watch the clip above!

We wonder if it's working!

On Saturday night Selena Gomez and her former Wizards of Waverly Place co-star David Henrie had dinner at Il Cielo in Beverly Hills, and given how sexy Selena is dressed, we have a very hard time believing this was just a friendly catch-up. And not only that, but SG was holding some flowers on her way out of dinner -- take that, Justin Bieber! We can't even remember the last time the pop superstar took Selena for a romantic evening on the town and bought her a bouquet of roses.

Henrie is 25 years old, and after life on the Disney Channel, he's found success on the small screen (most notably in a recurring role on How I Met Your Mother) and he has several movies in the works. Henrie dated Pretty Little Liars babe Lucy Hale from 2007-2009, and this isn't the first time he's been seen with Gomez. Back in the summer of 2013 the two went out to lunch and dinner a few times, and Selena was even spotted leaving his house.

Just a few days after Gomez released the music video for "The Heart Wants What It Wants," in which she pathetically pines for her former flame, the Biebs unfollowed her on Instagram. But after looking at the smile on her face and her social media posts over the last few days it seems like Selena is on the mend -- and perhaps even on the rebound!

Kourtney Kardashian's adorable son Mason celebrated his fifth birthday over the weekend, and the family all dressed up as characters from The Nightmare Before Christmas at the party! Well, MOST of them.

Khloe shared some spooky snapshots on Instagram and wrote, "Kourtney pulled a "mean girl" move on me and had me dress like Sally from The Nightmare Before Christmas," adding that "everyone else was mad chill. lol thanks @kourtneykardash #MasonsBirthdayBash."

The Kardashian family's makeup artist Joyce Bonelli painted the ladies' faces, and while Kendall didn't go as crazy as Khloe with the theme, Kylie seemed to think she was exempt from showing up in a costume. Some nerve!

And speaking of makeup and the Kardashians, yesterday it was announced that supermodel-in-training Kendall is the new face of Estee Lauder! She turned 19 less than two weeks ago, so talk about a great belated birthday gift!

"Here comes the big news," Kendall tweeted on Saturday. "It's w/ me and @esteelauder - and @voguemagazine has all the deets. I am super excited to announce that I am the new face of @esteelauder!!" Check out the video below -- and congrats to one of our fav members of the Kardashian household!

Miley Cyrus and new beau Patrick Schwarzenegger went to dinner at Katsuya in Brentwood on Saturday night, and the two 21-year-olds were all dolled up for their sushi date -- and they couldn't keep their hands off of one another!

Miley couldn't stop smiling when she hopped in the car with her bf, and we think it's interesting that she kept her fashion relatively demure. Her Instagram feed is still all kinds of crazy, but is it possible that Patrick is taming the pop star's wild style?

After sneaking around for the first few weeks they were together, the new couple confirmed their romance at the USC football game earlier this week when they shared a kiss in the crowd. The day before that Patrick brought Miley to the premiere of his mom Maria Shriver's upcoming film, Still Alice (she's a producer -- and the film has been getting some major Oscar buzz), and the group hung out at Maria's Brentwood home after that.

From public smooches to meeting the family, it certainly seems like this is getting serious very quickly! But here's what we wanna know: What does Arnold think about his son romancing the headline-grabbing singer? And what does Patrick have planned for Miley's 22nd birthday next week?

She's still got it!

Christina Aguilera is now a mother of two but showed that she could still bring the house down with her pipes as she made her first official appearance at The Breakthrough Prize Awards to perform her 2002 hit Beautiful. We knew she had it in her!

The 33-year-old singer also stunned in a long-sleeved red gown while fiancé Matt Rutler, son Max and her new baby girl Summer Rain along with the rest of the audience watched in awe.

Xtina has kept things low key since Summer's birth in August but clearly she's on top of her game. She's lost the baby weight and has signed on to season 8 of The Voice for good measure. Things are looking up!

Check out a clip of Christina's performance above and watch the Breakthrough Prize Awards in its entirety when it airs Saturday, Nov. 15 at 6 p.m. ET on the Science Channel and the Discovery Channel.
