Funnyman David Spade is to become a dad for the first time after his ex-girlfriend named him as the father of her unborn child.

Playboy Playmate Jillian Grace, 22, claims she fell pregnant with Spade’s baby after dating him for a short period last year.

And the 43-year-old has vowed to support Grace if her claims of paternity prove to be correct.

He tells TMZ.com, "I had a brief relationship with Jillian Grace. If it is true that I am the father of her child, then I will accept responsibility."
