Khloé Kardashian throws exclusive birthday party for Lamar Odom in the Hospital

Lamar Odom celebrated his 36th birthday on Friday with a small birthday party at Cedars-Sinai Medical Center in Los Angeles, a source close to the former NBA star told PEOPLE. The get-together was made possible by Khloé Kardashian, who was at the hospital with sister Kim Kardashian West and mom Kris Jenner, who has her own 60th birthday bash planned for Friday night.

Khloe reached out to Odom's former teammates as well as two of his best friends that are not NBA players and invited them to the get together. Kobe Bryant will not be able to attend because he's on the road but will send a gift and connect with his former teammate via FaceTime.

The party took place in a separate private room. Khloe arranged for a cake, balloons and party hats.

The source added that only a select amount of people could attend, and Kardashian had the get-together approved by his doctors.

"It's just a very small group of people because Lamar cannot handle too much stimulus, but the doctors are allowing a small group for a short time on his birthday," the source said.
