Life & Style has obtained exclusive photos of the couple on a romantic Connecticut getaway. On July 19, Demi and Martin went to lunch at Nine Main Bakery and Deli in New Preston, Conn. "She was in line and a Colbie Caillat song came on -- she started singing along and dancing in a playful, flirty way," shares a fellow diner. "They were very comfortable with each other."

Three days earlier, they'd enjoyed a lobster dinner at a friend's house, followed by a two-hour hike at Steep Rock Preserve the next morning. Later that night, Demi and Martin, 37, joined pals for a casual outdoor barbecue. "They just kept chatting and laughing," reports a guest. "She looked great -- chatty, healthy and happy."
