Pharrell celebrated his birthday and Saturday Night Live gig with a star-studded soiree in New York City over the weekend. While his guests included everyone from Alicia Keys to Hot 97's Miss Info, the real VIPs were Nickelodeon superstars SpongeBob and Patrick. Hey, with an upcoming role on NBC's The Voice, he's got to learn the ropes from TV veterans.

Kristen Stewart said goodbye to her brunette locks over the weekend, in preparation for her upcoming role in American Ultra. The Twilight star stopped by Maison de Cheveux in New Orleans, La., and walked out with an alluring strawberry blonde/orange shade. (Sigh. We wish we could blame our questionable hairstyles on work.) Kendall Jenner made the most of her family's trip to Thailand by pushing any fear of heights to the wayside, while sister Kourtney Kardashian reminisced about the old days with partner Scott Disick and Kylie Jenner had some girl time (aka sexy staged selfie shoots) with new pal Selena Gomez. Meanwhile, someone whose name rhymes with "Fever" got a new Bugatti. Don't let his inevitable cover of Ace Hood influence you, Selena!
