Actor-comedian Kevin Hart is recovering well after back surgery following the horrific car crash, said his wife Eniko.

"He's great. He's going to be just fine," Eniko said in a video obtained by "TMZ".

"He's good. Everybody's good, thank God," she added, also pointing out that Hart is awake and recovering.

According to a source, the comedian is expected to remain in the hospital for at least a couple of days.

Hart suffered severe back injuries and was hospitalised following a major car crash in California. The accident happened on Sunday on the winding and treacherous Mulholland Highway. Crash scene video, shows Hart's car deep in a gully about 10 feet off the road.

The vehicle smashed through wooden fencing along the roadside, and its roof was completely crushed.
