She sure knows how to dress down!

Britney Spears looked a little too comfortable on Thursday as she arrived at the Beverly Hills Hotel armed with her dog and a pack of cigarettes all while rocking a pair of spandex with a hole in it. Did she ditch her stylist?

Even though the 31-year-old pop star has been going through a whirlwind of activity in the past few months, that's no excuse for sloppy style. Maybe she's too busy working on her new album to bother?

She's just busting out everywhere!

On the same day that she debuted her budding baby bump on Instagram, Kim Kardashian showed some serious cleavage to go along with out in Los Angeles on Thursday. Mama mia!

The curvy soon-to-be mom went for a quick workout at the Tracy Anderson gym in Studio City before stopping by the Andy Lecompte salon in West Hollywood for some pampering. Kanye West would be proud!

Isn't she just gorgeous?

On Thursday, Jennifer Lawrence made sure her street style was intact when she wore a beautiful teal dress on her way to Jimmy Kimmel Live! in Hollywood.

The 22-year-old Silver Linings Playbook actress is bouncing back nicely after her little wardrobe malfunction at the Screen Actor's Guild Awards last Sunday that occurred when she was going to accept her actor award.

We knew that mini mishap wouldn't keep her down!

Another tough day at the office!

Alessandra Ambrosio is currently in St. Barth posing for a sultry Victoria's Secret photo shoot, and the mother-of-two makes her job look easy! In between takes, the brunette beauty was glued to her cell phone, and we bet she was checking in on her two young children!

For Miss Ambrosio, life these days is only about family and fashion. Unlike some of the other Angels who party with Leonardo DiCaprio on their off time, this 31-year-old seems completely content living a quiet home life with beau Jamie Mazur, daughter Anja and son Noah.

Life is good when you're beautiful!

We can finally see it!

Kim Kardashian was on set for what looks to be another photo shoot with her sister Khloe today, and the reality star decided to give us the first glimpse of her growing baby bump! Although she's stepped out almost every day since announcing her pregnancy, this is the first time we've seen her in figure-hugging clothes that actually accentuate her expanding waistline.

"Well hello there! #PoppedOuttaNowhere!!!" the brunette beauty captioned the snapshot.

When it does come time to give birth, Kimmy K might be getting more help from her famous sisters and mom than her rapper beau.

"Emotionally, Kanye wants to be there for Kim throughout the labor, but he's just not sure he's up to it. He is embarrassed about it, but Kanye has always fainted at the sight of blood. And he feels very squeamish at the thought of watching the birth. The truth is, Kanye is scared he will just add to Kim's anxiety during labor," a source dished to Showbiz Spy.

If Yeezy can't handle it, we're sure Kris Jenner will be more than happy to pick up the slack!

So this was what she was saving her pipes for!

Beyonce Knowles performed a live rendition of the National Anthem at a Super Bowl press conference on Thursday in New Orleans, and after belting out the "Star Spangled Banner," the singer chatted with the audience, finally addressing her lip syncing scandal.

"I am a perfectionist and I practice until my feet bleed and I did not have time to rehearse with the orchestra," she said. "Due to the weather, due to the delay, due to no proper sound check, I did not feel comfortable taking the risk, so I decided to sing along with my prerecorded track, which is very common in the music industry. And I'm very proud of my performance."

"Typically, they have you sing a pre-recorded track in case something goes wrong," she added. "I was singing along with the prerecorded track ... I will absolutely be singing live [at the Super Bowl]. I am well rehearsed and I will be singing live ... this is what I was born to do."

Is she anxious about her halftime performance on Sunday? Yup! "I'm nervous," she said. "When I was driving up, I got chills looking at the Superdome. There's so much history there."

We can't believe how big Sarah Jessica Parker's twin daughters are getting!

SJP, Marion and Tabitha were snapped going for a stroll in New York City on Wednesday with their nanny, and both of the little girls had tons of energy. We still can't tell them apart, but the former Sex and the City star gave one a smooch and the other one got quite a thrill when the group crossed the street:

Leann Rimes is known more for parading around in bikinis than for her fashion sense, but that doesn't mean she doesn't have millions of designer pieces to choose from!

"Leann's closet is huge. It has a window and a place for accessories, and shoes going up every single wall," stylist Mary Alice Haney explains on the new episode of Celebrity Closet Confidential.

The show aims to polish different celebrities wardrobes and update their overall look.

"I want to make her more polished and sophisticated without losing her sexiness," Haney adds.

The celebrity stylist ultimately decides to draw style inspiration from the Grammy winner's wedding dress. "Leann's wedding dress was exactly the right amount of sexiness and sophistication. I want to take that and incorporate it in every other aspect of her fashion life," she declares.

Pieces chosen include a Bottega Venetta dress, a Missoni cover-up, and a Tom Ford formal dress. All of Leann's discarded items were donated to charity.

Celebrity Closet Confidential airs on January 30 on the Style network.
