The Kardashians -- well, maybe not Kim -- are ready to party!

On Monday night, reality TV's most famous family were in a celebratory mood. Khloe Kardashian's husband Lamar Odom turned 32 on Sunday, so his wife and the bulk of his in-laws hit El Floridita cuban restaurant in Los Angeles following Rob Kardashian's performance on Dancing with the Stars.

The birthday boy was joined by wife Khloe, 27, Rob, 24, Kourtney Kardashian and beau Scott Disick, their son Mason, parents Kris and Bruce Jenner plus Rob's DWTS partner Cheryl Burke and fellow pro Mark Ballas and three other pals.

Kim Kardashian, however, was a no-show for the bash; the divorcee-to-be arrived back in L.A. Sunday evening after a quickie visit with Kris Humphries to hash out details of their impending divorce and to reach "closure," according to one source.

The raucous dinner -- which included champagne, cuban food, plenty of silly photo opps and salsa dancing! -- was taped for an episode of Khloe and Lamar.

"It was a fun night," an observer said. "Lamar has been going here ever since he played for the Clippers. It's one of his favorite restaurants."

And while her absent 31-year-old sister's marital fairy tale went up in smoke, Khloe looked overjoyed to celebrate her hubby of over two years.

"She looked so happy!" another observer noted. "They are a really great couple. They looked very loving and supportive with one another."
