Justin Bieber is notorious for his love of baring his chest and going shirtless whenever possible, and it appears his entourage has fallen for the fad as well.

The pop sensation and pals sported matching black undies as they showed off their abs and caught some sun at the singer's Calabasas home, and his bestie Lil' Twist decided to share a snapshot of the group in all their glory.

From the looks of it, The Biebs has been busy at the gym, because his guns have never looked so ripped before!

Ladies, eat your heart out!

Looks like she's taking cues from Jennifer Garner!

Earlier this summer we spotted Ben Affleck's wifey taking her brood to the Natural History Museum in Los Angeles, and on Thursday Gwen Stefani brought sons Zuma and Kingston to the same spot for a little extracurricular adventure.

Gwen kept it casual in a black tank and loose pants, but rather than wearing flip flops in the 95-degree weather, the No Doubt singer wore boots. BOOTS! We're eager for fall fashion too, but geez!

She can't stop... and she won't stop!

Miley Cyrus is busy promoting her upcoming album Bangerz, and the raunchy singer must figure the best way to drum up press is by posing for sexually provocative photo shoots and promotional shots!

The former Disney star is on a mission to prove she's all grown up, and in one of the promo images, the blonde wild child poses in a sports bra and checkered pants as she stares seductively into the camera and grabs her crotch. In the other, she sports slicked back hair and a PVC top while she holds colorful balloons.

Seeking even more attention, the engaged songstress covers the latest Notion magazine and shows off her amazing physique in a variety of body baring ensembles.

At least she gave the twerking a rest for long enough to take some pictures!

Lamar Odom was released from jail after his D.U.I arrest early this morning in the San Fernando Valley, and officers at the Van Nuys Community Police Station tell X17online exclusively:

"Lamar's attorney came to pick him up at 8:33am. The attorney posted $15,000 bail and the two left in the same car."

California Highway Patrol pulled Odom over at 3:54am on Friday on the 101 freeway in the San Fernando Valley after noticing that he was driving in a "serpentine manner" and going only 50 miles per hour. Lamar drove past 3 exits before he finally stopped his vehicle, and law enforcement sources say he showed "obvious signs of intoxication."

We can't imagine what Lea Michele must be going through. A little over a month after the loss of her boyfriend and co-star Cory Monteith, the Glee star celebrated her 27th birthday on Thursday -- her since the death of Monteith. But despite what we imagine to be a difficult day, Lea took time to thank her fans for their support during the trying times.

“Thank you guys for all the birthday love today:) So beyond thankful for all of you …,” tweeted Lea.

The New Year's Eve star has been putting on a brave face since the news that Monteith had died of a overdose from a mixture of heroin and alcohol in his Vancouver hotel room on July 13. At the 2013 Teen Choice Awards on Aug. 11, the brunette singer/actress made an emotional and heartfelt speech when she dedicated the her Choice TV Actress -- Comedy award to her fallen love.

“I wanted to dedicate this award to Cory,” Lea said onstage at the awards show. “For all of you out there who loved and admired Cory as much as I did, I promise that, with your love, we’re going to get through this together.

We are amazed at Lea's strength during this ordeal and wish her the best birthday. The fifth season of Glee comes back to FOX on Sept. 26.

Her housemates wish she would cover up!

Courtney Stodden has only been in the Celebrity Big Brother house seven days and already she's managed to ruffle feathers by parading around in skimpy outfits and showing off her ample assets. Most recently, the teen bride decided to lay out and get a tan in a small black bikini that didn't do a very good job keeping her implants covered.

The blonde bombshell turned 19-years-old yesterday and won a challenge on the show that rewarded her with a birthday party complete with cake, pizza, and champagne, and she chose to share her celebration with fellow castmate Dustin Diamond.

When is this girl going to learn to put on clothes?!

Aww, she may be an ice queen sometimes, but she's got a soft spot for her hubby!

Rachel Zoe and Rodger Berman celebrated their 22nd wedding anniversary in Bridgehampton, New York last night, and the duo posted the adorable shot above and wrote, "Happy anniversary to us!!! 22 blissful years @rbermanus....xoRZ." RZ also posted the throwback shot of the two of them below and added, "OMG...had to post this #tbt - how cute is @rbermanus?! :)"



The couple dined with designer Brian Atwood and his partner Jake Deutsch, and the celeb stylist tweeted, "Can't imagine a better couple to share our anniversary with! My loves @brian_atwood & @drjakedeutsch." Sounds like a blast!

She really is a fighter! Despite the fact that her 2012 album Lotus was considered a flop, Christina Aguilera is refusing to give up on it. The Grammy winner is releasing a new single, "Let There Be Love," off the album as well an accompanying video that features her adorable son and famous friends Nicole Richie and Christina Milian. And lucky for us all, Xtina also shows off her newly fit form in a few revealing bathing suits.

At the start of the video, the "Fighter" singer opens up with a personal message to her fans, saying, "Hey everybody Christina here, just thanking you guys so much for filling my life and my heart with so much love continued throughout the years. Standing by me, I appreciate all your support, this one is just for you."

In the music video, fan clips are spliced with home videos of the 32-year-old songstress and her pals, including Nicole Richie, who is seen joking around with another friend as they make the "L" sign for love with their hands. Throughout the music morsel, people fans and friends are pictured making the L, as well as holding pro-tolerance signs like "Racism sucks," "Respect," "Accept" and "War is not the answer."

Viewers can even glimpse the sexy lady's too-cute son, five-year-old Max Liron Bratman rocking out to his mom's music (he's the wee one wearing burgundy pants, a Batman shirt, converse and a fedora). Oh my gosh -- we think it's beyond adorable!

While we love the positive message of the fun-filled video -- we wonder if anyone mentioned to the crooner that the "L" sign stands for Loser? Either way, we are digging this song and hope Xtina turns this tune into a chart winner!
