The reality star celebrated turning 31 with an intimate dinner at The Darby on Friday evening. Kim was joined by her new husband Kris Humphries, her sisters Khlo and Kourtney and Scott Disick.

The newlyweds shrugged off speculation their marriage is already on the rocks by putting on a united front.

They kissed and danced while Pink performed Killing me Softly with the house band. Kris smilingly picked Kim up and hugged her, before Kim shouted "I love him!" into a microphone.

He also presented Kim with her birthday present - a huge, heart-shaped pave diamond necklace.

At the end of the evening a stunning birthday cake was delivered to the star's table. Kim's close friend La La Vazquez Anthony led the guests in a rendition of Happy Birthday.

Other famous faces who attended the bash included Nick Lachey and Joyce Bonelli.

Kim continued her birthday celebrations by partying in Las Vegas' Marquee club last night.

It has been revealed Kim has landed a role in Tyler Perry's new movie. In The Marriage Counselor, the beauty will play Ava who gives her therapist friend a makeover to boost her confidence.

Shooting is scheduled to begin in Atlanta next week. (C) Cover Media
