"She was in line and a Colbie Caillat song came on -- she started singing along and dancing in a playful, flirty way," a fellow diner said.

"They were very comfortable with each other," notes a fellow diner.

The pair also went on a hike, and joined their friends for a bbq -- and even at a private function their friends want to sell details of their relationship to the press!

"They just kept chatting and laughing," reports a guest.

Yet another insider added, "She looked great -- chatty, healthy and happy."

Who is Martin Henderson? He's a Kiwi actor who has also appeared in Australian shows like Home and Away (way back in 1996), plus Hollywood films Bride and Prejudice and The Ring.

Demi is also continuing her cougar ways -- at 37, Martin is 12 years younger than her.
