Imagine being a singer who steps out of her comfort zone to host a talk show. Kelly Clarkson's talk show debuts on Monday! Girl must be so nervous. Well, check this out. Her very first guest was supposed to have been Kevin Hart!!! Ahhhh! Obviously, as he's recovering from last weekend's car accident, he won't be able to make it. Fortunately, his good friend Dwayne "The Rock" Johnson has offered to fill in for Kevin. He even cut his honeymoon short to fill in. Luckily, The Rock's wife is a Kelly Clarkson fan.
