There might be a sign that Lamar Odom is responding to treatment at Sunrise Hospital in Las Vegas. He’s been there since Tuesday after he was found unresponsive at a legal brothel.

Sources told TMZ that the former basketball star’s heart function is “much better” after tests this morning. Doctors told those close to Odom that this is good since the heart is responding. Doctors asked that everyone by his side be calm because they don’t want him suddenly excited or to make any sudden movements.

However, USA Today Sports reports that the TMZ report might be overly optimistic at this point, citing a source at the hospital.

Odom was rushed to the hospital following three consecutive days partying at a brothel. It was reported that he had used cocaine and 10 sexual performance pills, but the toxicology report still hasn’t been completed.

Khloe Kardashian, Odom’s estranged wife, is reportedly staying by his side. Their divorce is still not finalized, so they remain legally married.

Meanwhile, there were rumors that Caitlyn Jenner had visited the Las Vegas hospital, but those rumors have been debunked.
