Dwayne Johnson leaves honeymoon early to fill in for injured Kevin Hart

Dwayne Johnson is Kevin Hart's rock.

Johnson left his honeymoon early to fill in for Hart on "The Kelly Clarkson Show" after his friend and co-star was hospitalized with a major back injury over the weekend.

Hart was scheduled to be Clarkson's "first guest ever" on her new syndicated talk show, she said. "Because Kevin couldn’t be here, one of his good friends stepped the heck up and I love him. … His wife probably hates me," Clarkson added.

However, the "Hobbs & Shaw" star said his new wife, Lauren Hashian, actually "approved" of him leaving their honeymoon early because "she LOVES Kelly."

A California Highway Patrol collision report obtained by USA TODAY says Hart was a passenger in his 1970 Plymouth Barracuda when it went off Mulholland Highway and rolled down an embankment Sunday.

The report says Hart and the driver, Jared Black, 28, suffered back injuries in the crash. Another passenger, Rebecca Broxterman, 31, only complained of pain.

Hart went to his home nearby to get medical attention before heading to Northridge Hospital Medical Center, according to the report.
