Dwayne 'The Rock' Johnson has prematurely returned from his honeymoon to replace his friend Kevin Hart in The Kelly Clarkson Show . Hart was injured early this week after a car accident and therefore his planned performance in the talk show could not take place.

Clarkson was visibly surprised when Johnson appeared on her show. "His wife hates me now, probably," said the singer and presenter.

"If my son Kevin is injured, his father comes to save him," tweets Johnson. "I left my honeymoon prematurely - Lauren likes that because she's a big fan of Kelly - and now Kelly and I are best friends."

Johnson gave the answer to Lauren Hashian two weeks ago and they went on a honeymoon. The actor and the 34-year-old singer have known each other since 2006 and got into a relationship a year later. They now have two daughters together, Jasmine (3) and Tiana Gia (1).

Hart became involved as a passenger in a car accident last weekend and then had to undergo a back surgery. He will have to recover from this in the coming weeks, but according to his wife "it will be all right again" with him.

The episode with Clarkson and Johnson can be seen on 9 September on the American channel NBC. The Because of You singer makes her talk show debut with this.
