Vince Vaughn is going to be a dad again.

The "Wedding Crashers" star will announce on Monday's episode of "Ellen" that he and his wife, Kyla Weber, are expecting another baby.

"We're expecting our second child," he says in their interview. "We're very excited."

Vaughn, 43, and Weber welcomed their daughter Locklyn in 2010 - one year after they got married.

"I met the best girl in the world," he has said of his wife, who is due in August. "It gives you such a great purpose in my life. If I would've met her, I would've done it a long time ago."
