Jennifer Lopez and Casper Smart made a stylish appearance at Hakkasan Nightclub's grand opening at the MGM Grand in Las Vegas on Saturday. Jennifer stunned in a clingy little black dress while her boyfriend rocked a bright red blazer on the carpet. Inside the club, the duo mingled with Vanessa Hudgens, her boyfriend, Austin Butler, and dancer Cheryl Burke, while other celebrity attendees like Glee's Mark Salling, birthday boy Pharrell Williams, and Paris Hilton spent the night listening to Calvin Harris DJ the event.

Over the weekend, J Lo had more than just Sin City fun on her mind since her son, Max Anthony, got stitches for a minor chin injury while in LA with dad Marc Anthony. J Lo addressed the situation on the red carpet, saying, "Of course I was freaking out, but he was fine. He said it tickled." Back on the work front, J Lo is prepping to launch her next single, "Live It Up," with Pit Bull on May 8. In addition to new music, J Lo may be returning to TV after rumors surfaced earlier this month that she'll return to American Idol's judging panel as a replacement for Mariah Carey. Producers have denied the replacement assumptions, but no comments have been made regarding whether Jennifer will return to the show next season.

Miley Cyrus and Jennifer Hudson celebrated Pharrell Williams's 40th birthday in Miami on Friday night. Miley bared her belly in a black crop top and baggy leather shorts as she mingled with the star-studded crowd. She and Pharrell have become close friends after he started collaborating with her on her upcoming album. Miley hasn't confirmed when the new record will come out, but she did give fans a taste of her new sound last week when she and Snoop Dogg released a new single together titled "Ashtrays and Heartbreaks." She has been spending the weekend in Miami and was spotted smoking a cigarette with a male friend on a hotel balcony on Saturday.

Happy Thanksgiving! Getting together with family and prepping for the special meal kept celebs busy this week. They got to work in front of and behind their own personal cameras, sharing lots of sweet and sexy photos through social media. Justin Bieber snapped a pic from the road, and Oprah Winfrey got busy in the kitchen. Diddy hung out with his family, and Smash's Katharine McPhee went wild with accessories.

It was a special night in Brooklyn yesterday when Jay-Z opened the Barclays Center with a sold-out concert that kicked off a string of upcoming performances. The stadium is the new home of Jay-Z's Brooklyn Nets basketball team, and he shared on stage, "I want to thank you, Brooklyn, New York City, for making me the man I am today. Like I said, everybody's from Brooklyn tonight." The celebration continued when Jay-Z and his wife, Beyoncé Knowles, partied postshow at the D'Usse VIP lounge inside the venue. Jay-Z and Beyoncé launched the special D'Usse cognac with a bash at NYC's La Marina restaurant earlier this week.

Jay-Z was the center of attention last night at the launch party for the new cognac, D'ussé, at the Top of the Standard. He went to the NYC hotel despite the big playoff game going down between the NY Knicks and the Miami Heat. That wasn't a problem for Jay-Z though — the Standard wheeled out a big screen so Jay could watch the action in his VIP area. Beyoncé Knowles didn't join her husband, but her little sister Solange was on hand along with Pharrell Williams and a bearded Jake Gyllenhaal, who politely declined being photographed when he arrived just before 10 p.m. Jay-Z was also treated to a soundtrack of his own greatest hits at the Standard, since DJ Jus-Ske played "Otis" and more for the crowd. Beyoncé and Jay-Z were together on Tuesday evening, when they attended a bash for mutual friend Erica Reid's new book.

Cameron Diaz and Charlize Theron were among the stars who headed to the Chateau Marmont in LA on Tuesday night. The ladies attended a party thrown by Target and Bevy Smith to honor Pharrell Williams, who proudly took a seat next to Charlize at the dinner table. The celebs gathered at the Chateau's Bungalow One to raise a glass in honor of Pharrell scoring the music for this year's Oscars with renowned composer Hans Zimmer.

Cameron and Charlize made the rounds chatting with Usher, Johnny Knoxville, Jared Leto, and photographer Terry Richardson. Chelsea Handler even made a cameo with her possibly on-again boyfriend Andre Balazs, who happens to own the Chateau Marmont. Ellen Pompeo and her husband Chris Ivery also mingled with Pharrell and friends, as did MOCA director Jeffrey Deitch.

New York Fashion Week is starting to wind down, but yesterday boasted some of the biggest shows of the season and Rachel Zoe was front row to check out Proenza Schouler's Spring 2012 collection. The runway was covered in shag carpet, and the models strutted down the catwalk in Proenza Schouler eelskin skirts and prints. Rachel was joined in the audience by Alexa Chung, Pharrell Williams, and Alicia Keys. It's been an action-packed week for Rachel Zoe, who has taken in tons of shows alongside husband Rodger, and she also showed off her own Rachel Zoe collection with a private presentation. Rachel and Rodger's baby son, Skyler, was front and center to check out his mom's hard work. Rachel admitted she was "terrified" for her first-ever fashion week presentation, but it went off without a hitch.
