Kevin Hart underwent successful surgery to stabilize his back hours after he was in a serious car crash near his home in Calabasas, California.

Hart, 40, sustained a "major back injury" in the single car crash around 1 a.m. Sunday. He was riding in his vintage 1970 Plymouth Barracuda muscle car when his friend, who was driving, lost control of the high performance vehicle and it left the road on Mulholland Drive in Calabasas.

The car, which is a pricey collector's item, landed on the roof and rolled over. The driver suffered back injuries and was transported to a hospital. Hart's personal trainer, Rebecca Broxterman, was also in the car, but she was not injured.

Broxterman, 31, a popular Instagram fitness trainer, is said to be the fiancee of the driver.

Hart was the first one to climb out of the mangled vehicle after the crash, according to a witness. He reportedly called a member of his security team who arrived in a SUV to pick him up and take him home. He was later transported to a hospital.

Sources tell The Blast the comedian underwent successful surgery to "stabilize his back" late Sunday night, and he is expected to recover fully.

The source said "the surgery went smoothly, and he is doing ok. The surgery was a complete success. The doctors completed a procedure to stabilize his back."

Hart's wife, Eniko, has been by his side at the hospital and she is talking to doctors about his care.

Rumors are running rampant that Hart's injury is much more serious than his camp is letting on.

But a source tells The Blast the "Jumanji" actor did not injure his spinal cord, and that the comedian was able to "walk and move his extremities."
