The Rock's sweet Carell kiss

The Rock Dwayne Johnson

The Rock says kissing Steve Carell was like the first time he ate a "warm chocolate fudge brownie".

The former WWE wrestler, real name Dwayne Johnson, locks lips with comedian Steve in new movie 'Get Smart' and admits the experience was more enjoyable than he expected it to be.

Dwayne, 36, said: "You know the very first time you had a warm chocolate fudge brownie with ice cream? Sprinkles? Whipped Cream? That is what it was like kissing Steve Carell."

The father-of-one - who announced last year he and wife Dany Garcia were splitting after 10 years of marriage - also joked he and Steve are now in a relationship following the movie, but are trying to keep it a secret.

When British TV presenter Rick Edwards asked him if there was any chance of him and Steve enjoying a romance off-screen, Dwayne laughed: "Well it's not really a case of is there any chance, it's the fact that we are. Privately we are. I mean we have to really keep it private as he's married and he does have kids!"

'Get Smart', which also stars Anne Hathaway, is in cinemas worldwide now.
