Khloe Kardashian Plans Lamar Odom's 36th Birthday Party in the Hospital

Lamar Odom celebrates his 36th bday with Khloe Kardashian and his closest friends.

Although Lamar Odom will celebrate his 36th birthday in a hospital on Friday, he'll still be surrounded by his close friends and loved ones, including Khloe Kardashian.

The 31-year-old reality star planned a small birthday party for Odom at Cedars-Sinai Medical Center in Los Angeles, a source confirms to ET, and even reached out to a few of his former teammates as well as his non-NBA player best friends. The party is set to be in a private room, complete with a cake, balloons, and party hats. The doctor-approved get-together will be extremely small, due to Odom's still fragile medical condition.

Odom's former teammate, Kobe Bryant -- who has previously visited him in the hospital -- is expected to connect with him via FaceTime, as well as their fellow Lakers player Ron Artest. His longtime trainer is also expected to stop by the hospital.

Kardashian Instagrammed a picture of her shoes and stylish backpack on Friday, which appears to be taken from the hospital.

She's also expected attend her mother Kris Jenner's Great Gatsby themed 60th birthday party later Friday night -- which reportedly cost $2 million -- at a soundstage in West Hollywood, California. 

Odom's aunt, JaNean Mercer, released a statement Friday honoring his big day.

"Happy Birthday Lamar! We want to THANK everyone from around the world for your continued prayers and well wishes for Lamar and our family," she said. "Every birthday with Lamar is special but today is an especially momentous occasion and we honor GOD for this day and thank HIM for allowing us to spend this time together. Please continue to keep Lamar and our family in prayer as he continues on this miraculous journey."

Odom's health is continuing to improve only a few weeks after he woke up from a medically induced coma. On Thursday, a source told ET that the former NBA pro is now able to walk with the help of a walker, and people holding him up. He is expected to be able to move around on his own in a week or so.

"He is doing better but he has a long road ahead," the source also cautioned.

ET was also told that Odom has been allowed visitors as his health continues to improve, but it's up to him who gets to visit.

Odom and Kardashian called off their nearly-finalized divorce on Oct. 21. The Keeping Up With the Kardashians star has been by Odom's side since Oct. 13, when he was found unresponsive at the Love Ranch brothel in Crystal, Nevada.

Earlier this month, Kardashian talked about her current relationship with Odom.

"There is so much more medically and emotionally that we have to go through in order to even think about anything romantically," she told Yahoo! Style. "This is a very serious situation with a lot of layers. He has a long road ahead of him, and I will be there by his side. I will always love him unconditionally. That will never waver coming from me."
