A video posted by Justin Bieber (@justinbieber) on Sep 12, 2015 at 6:00pm PDT

Justin Bieber attended the Mayweather/Berto fight in Las Vegas on Saturday night, but before cheering on his boxing buddy, he got his drink on at a pre-party. And what better way to get tipsy in Sin City than to shotgun a beer?

Biebs and a pal poked holes in their cans and guzzled them down as fast as they could, but the pop star put on a pathetic showing -- and looked like he had gotten socked in the face when it was all done. "I lost but I didn't go to college," he captioned the video above. At least he's a good sport about it!

While Biebs has been pretty good about staying out of trouble lately, he did snap at a camera man for Today last week during a performance, and he broke down into tears at the MTV VMAs two weeks ago while performing his new song, "What Do You Mean." Keep it together, Biebs!

We can't get over how much Nori looks just like both of her parents -- and the fact that she often dresses better than them too!

On Saturday the 2-year-old celebritot rode in her nanny's arms to a New York Fashion Week event, and she rocked a pair of oversize aviators, a denim jacket and denim capris. So cute!

Parents Kim Kardashian and Kanye West have been busy with parties and shows, and while Kim is bumping her pregnant belly around town, Kanye is prepping for his Adidas x Kanye West show on Wednesday. We can't wait to see what he drops then ... we already know it's going to be footwear, but what else?

Kim Kardashian may be about 6 months pregnant, but that's not stopping her from wearing some of the sexiest outfits ever!

On Saturday night the reality starlet stepped out in a short leather skirt, thigh high boots and a top that showed off plenty of cleavage, and she looked amazing. According to recent reports Kim hasn't been feeling so hot during her second pregnancy, so kudos to her for going the extra mile in the wardrobe department!

The previous night Kim attended the Givenchy show, and she posed for a selfie with none other than Courtney Love. Kim posted another shot of her with Yeezy and added, “One of the best shows I’ve ever seen!” Well, of course, next to Kanye's! We hear he'll be putting on another show for his clothing collection next week -- wonder if any of the Kardashians will be working the runway?

Jennifer Garner attended the Think It Up telecast at Barker Hangar on Friday in Santa Monica, and she posed with Gwyneth Paltrow and Jessica Biel at the event. We had forgotten that Jen was friends with Jess -- the two met back in 2010 when they starred together in Valentine's Day.

Think It Up is a new movement in support of the nation’s students, teachers and schools, helping generate excitement about learning everywhere in America and building a sense of optimism about the changes underway in classrooms across the country, according to their mission statement. Celebs like Halle Berry, Kristen Bell, Jeremy Renner, Jason Bateman and Joe Manganiello were also in attendance, and they all wore shirts with the Think It Up logo.

This morning Jen was all smiles after her workout, so we have to wonder what's up with the actress and estranged husband Ben Affleck. Every other day there's a conflicting report -- first Jen wants him out of the house and then she's ready to take him back. We have a feeling none of these coffee drinks are for Ben though...

All we can see are boobs and stripes!

On Friday night Jessica Simpson and hubby Eric Johnson landed at Los Angeles International Airport, and she turned heads in this bold, striped jumpsuit. Jess was in NYC to promote her latest fashion collection, and the 35-year-old superstar chatted with a number of media outlets while in the Big Apple.

Of course, our favorite moment was when she sat down with CNBC and was asked what her biggest money mistake has been over the years. “The biggest money mistakes? I don’t know. For some reason I thought of my first marriage,” Jessica said with a laugh. Take THAT, Nick Lachey!

This may be our new favorite maternity outfit from Kim Kardashian...

On Friday night the pregnant reality TV star attended a New York Fashion Week event, and earlier in the day she stopped by the Givenchy show with hubby Kanye West at Pier 26. Though the duo were late, they did arrive just in time to support Kim's lil sis Kendall Jenner, who working the runway.

While she looks incredible, apparently she's not been feeling so hot. According to a source for E! News, “She is often uncomfortable. That being said, she feels much better this time around than she did with North." Aww, well she's only got a few months to go!

Stars - they're just like us!

Justin Bieber is back from his whirlwind trip to NYC, and we caught him sucking on a lollipop after leaving a doctor's appointment today in Beverly Hills. The singer donned shades and a hat as he made his exit, and we think he's embarrassed about his Today show outburst and trying to hide his face.

In case you missed it, JB threw a mini temper tantrum while performing on the morning show because the camera man wasn't capturing his dance moves. The problem? He didn't realize his mic was still on and the whole thing unraveled on-camera! The Canadian crooner has been making every attempt to repair his bratty reputation, so this can't have helped things.

To be fair, we could be totally overthinking things! Maybe The Biebs just isn't loving his new platinum blonde 'do?

We think she was better off sticking to pencil skirts and maxi dresses!

Kim Kardashian headed out for a day of shopping with her stylist today in NYC, and let's hope the reality star was on the hunt for a better outfit than the one she left the house in! We know that the brunette bombshell is doing everything she can to stay stylish and sexy with a bun in the oven, but we think it would be wise to stick to the basics until she gives birth. Poor girl just has a super awkward pregnancy body!

The E! starlet and hubby Kanye West have been enjoying some quality time in the Big Apple with their daughter North, and we're frankly surprised that Kris Jenner hasn't been following them around the city. Usually she is never one to miss out on the fun, and both Kim and Kendall are currently on the east coast for New York Fashion Week.

We wonder if Kimye approves of Kenny's budding relationship with Lewis Hamilton? Actually, who are we kidding - Kim doesn't care who her sisters date as long as they're famous and add to the family brand!
