Scott Caan and girlfriend Kacy Byxbee are expecting their first child together, his rep confirmed to Us Weekly.

“They haven’t been keeping it private really, she’s just been working on her business with her family so she hasn’t been around,” a source told Us. “She’s expecting very soon.”

Family, friends and her sisters feted the coming baby by offering Byxbee a baby shower last weekend in L.A., said the source.

The Hawaii Five-O star talked about his relationship with Byxbee during an appearance on Chelsea Lately in January 2013.

“She should get the purple heart because I’m a complete disaster,” he said.

The couple live together in Hawaii so Caan can shoot Hawaii Five-O. However, the 37-year-old hottie said the “relaxed” nature and lack of “hustle” in Hawaii — where the couple first met — isn’t exactly his idea of paradise.

“Everything’s very slow-motion. I pick up the cup and they slowly pick of the cup,” he joked.

This will be the first child for the couple who have been together for a “couple of years.”

Scott’s father, James Caan, is said to be very excited to become a grandfather.

“His dad James is really close with him,” the insider told Us. “He is very excited.”
