Bones actor David Boreanaz is to become a father for the second time.

The 39 year old star let the news slip during an appearance on morning show Live with Regis & Kelly on Wednesday, when he discussed how he explained "the birds and the bees" to his six year old son Jaden Rayne, with wife Jaime Bergman. He revealed, "(I said), 'Jaden, you're aware that mommy and daddy are having a new baby?'"

Co-host Kelly Ripa picked up on the mistake and prompted, "Did you just say you're having a new baby?" - To which Boreanaz replied, "I said that? Oh I did! Yes, I'm having a new baby."

The expectant couple has been married since 2001.
