The Final Destination star's girlfriend, actress Leah Renee, is pregnant with the couple's first child, her representative confirms to Entertainment Tonight.

Nick, 38, and Leah, 30, have kept their relationship low key, but the mother-to-be has been documenting her journey to motherhood online.

"I am VERY pregnant, by a pool, in Vegas," she tweeted in May (16), when she shared a snap of herself wearing a bikini and sunglasses.

Nick previously dated 2 Broke Girls star Kat Dennings and romanced Haylie Duff for three years until 2011.
