Alex O’Loughlin

Sharpen those fangs, Moonlight fans, because Alex O'Loughlin is close to booking a new big-screen appearance.

The Aussie actor, who starred at Mick St. John on CBS' cult vampire hit, is in talks to play the male lead in Jennifer Lopez's Back-Up Plan, according to the Hollywood Reporter.

Back-Up stars J.Lo as a woman who visits the local sperm bank in the absence of a main squeeze. But of course, her plan is upended when she meets the man of her dreams — the same day she learns she's pregnant.

If O'Loughlin inks a deal, Back-Up could mean an even busier spring for him. The hunky thesp is also appearing in Whiteout, opposite Kate Beckinsale, and he was just cast in the CBS pilot Three Rivers.

What do you think of O'Loughlin and Lopez meeting cute? Do they make a good pair?
