POTW: Ciara, Katy Perry, Kanye West, Beyonce

Kim Kardashian had an unofficial 30th birthday tag-along party at the TAO 10th anniversary party in NYC on Oct. 16. And who was by her side? Not a new athlete boyfriend -- move over Reggie Bush! -- but bestie Ciara, who helped Kim K. blow out the candles and make a wish.

Ciara helped BFF Kim Kardashian make a birthday wish, Katy Perry and Russell Brand hid from the paps, Kanye West greeted his NYC fans, Jay-Z launched "Decoded" in Miami, M.I.A. was in the Halloween spirit, Lady Gaga sent a thank-you note, Taylor Swift was pretty in pink, Beyonce proved she has no baby bump and Nick Jonas enjoyed a wholesome game of b-ball. It all happened this week and we've got the pics to prove it.
