Jennifer Lopez kicked off her "All I Have" Vegas residency last week with all the sparkly fanfare that one would expect from Jenny from the Block. But while fans were certainly expecting the glitz of her Swarovski crystal-encrusted Versace numbers, they probably weren't expecting J. Lo's world-famous booty to make its own cameo. That's exactly what went down Saturday evening, when the singer's bodysuit split mid-show. Like a true professional, Lopez continued the performance following the booty poppin' fiasco. [Elle]

Supermodel Coco Rocha's new line of contemporary sportswear, which features structured pieces with mesh details and modern geometric patterns created by her husband, artist James Conran, was revealed today on the model's revamped website. Called Co + Co, the collection was created in collaboration with the Los Angeles-based company Paragon Project. The full apparel line, priced between $80 and $300, will be available online as well as at select retailers in March. []

Nike's latest advertising venture is not your typical fitness ad. Instead of a photo shoot, the retailer announced a new shoppable YouTube web series called Margot vs. Lily, which follows two sisters who each struggle to overcome a personal challenge to win a bet. Lily, a successful type-A fitness vlogger, bets her lazy sister Margot that she cannot start her own successful fitness channel on YouTube; Margot challenges the uptight Lily to make new friends. The series, which is part of the company's Better for It campaign, debuts on on Feb. 1. [YouTube]

The second installment of Christophe Lemaire's collaboration with Uniqlo has arrived. Much like the wildly successful fall line, the spring collection is brimming with structured basics and light knits in crisp whites, blues and marigold hues. Pricing has yet to be announced, but the 33 new styles will hit stores and Uniqlo's site March 4. [Fashionista]
