David Spade with his new girlfriend leaving Koi Restaurant. Los Angeles, California - 03.06.08

The couple dated briefly last year (07), according to In Touch Weekly magazine, and now Grace has announced she is pregnant with the actor's baby.

The 43-year-old, who is 21 years older than the model, has yet to publicly admit the baby is his, but tells In Touch, "If it is true that I am the father of her child, then I will accept responsibility."
