Kim Kardashian Celebrates her Birthday

Newlyweds Kim Kardashian and Kris Humphries put on a big show of unity amid rumors of marriage trouble, kissing in front of other partygoers at The Darby in New York night while celebrating the socialite's 31st birthday. Reports Friday indicated that Kardashian had celebrated her birthday at the Museum of Natural History without Humphries.
With a camera crew recording the couple's every move, Kardashian and Humphries stood up and locked lips in front of the crowd at the small party that included sister Kourtney and her boyfriend Scott Disick, singer Pink and her husband, and several friends.
Pink gave an impromptu performance with the house band, singing "Killing Me Softly," but the chart-topping singer still hasn't gotten over stage fright -- before the performance she had her husband bring her a shot of whiskey to calm her nerves.
According to several reports from gossip magazines, Kardashian had become fed up with Humphries' partying while he is out of a job thanks to the NBA lockout. Humphries, 26, has been spotted in Miami and New York without his new wife, getting flirty with multiple women and "acting like a single man."
