Soon we’ll be saying “aloha” to a brand new addition of the Hawaii Five-0 family! The show’s leading man Scott Caan is going to be a daddy!

The 37-year-old and his girlfriend, Kacy Byxbee, are expecting a little one together, a source tells Life & Style. The couple actually met on the set of the CBS show, so obviously we have to suggest Danno, Jr. as a name if the tiny tyke’s a boy.

The couple have yet to officially confirm the news, but the Life & Style source says the intel came direct from a pal of the mama-to-be. “Kacy’s friend posted a photo of her very pregnant belly with the hashtag #babycaan on Instagram,” the insider spills.

“Very pregnant,” huh? Could Kacy be on the brink of her due date despite the news just reaching our ears now? We wouldn’t put it past the very private actor and his gal pal.

Despite coming from Hollywood royalty (Scott’s dad is actor James Caan), he’s kept an impressively low profile even with his success first on Entourage and then the Hawaii Five-0 reboot. Just check out the personal life entry for the guy on Wikipedia: “Scott Caan is a brown belt in Brazilian Jiu-Jitsu.” That has to be a record for the fewest words ever entered in any star’s Wiki page.

Share your congratulations for Scott and Kacy in the comments below!
