Scott Caan's representative has confirmed reports suggesting the actor is set to become a dad.

The Hawaii Five-O star's girlfriend Kacy Byxbee is expecting the couple's first child together.

Caan's rep tells Us Weekly magazine, "They haven't been keeping it private really, she's just been working on her business with her family so hasn't been around. She's expecting very soon."

Caan, the son of veteran actor James Caan, met his partner on the set of his hit Tv series.
