This is how gossip starts. Chace Crawford and rumored girlfriend Rachelle Goulding spent the holiday weekend together with his family aboard a yacht in Cabo San Lucas, Mexico -- and the pair didn't exactly hide their affection toward each other.

Both Crawford, 27, and Goulding, 26, kept their attire casual for the sunny vacation on Sunday, May 26, wearing black T-shirts and shorts -- red for her, blue for him. The couple both donned sunglasses as well, and the former Gossip Girl actor kept an arm around Goulding's shoulder as they strolled along the beach.

Crawford's sister Candice Crawford and her husband Tony Romo also came along for the family getaway. 

The actor and the Canadian model were first spotted getting cozy together at a New York Knicks game at Madison Square Garden on March 29. At one point, an onlooker told Us, Goulding leaned over to whisper in Crawford's ear as he flashed a big smile.

A source said at the time, however, that the pair didn't have "anything serious" going on between them. "They met in London last summer," the source said of how the two initially connected.

The actor has previously been linked to several Hollywood hotties, including Ashley Greene and Carrie Underwood, and Crawford is more sure now than ever of what he's looking for in a partner.

"It's the way they carry themselves, that confidence. I'm open to whatever," he said in an April 2012 interview with Pop Sugar Australia. "I love a girl who's really spontaneous, someone who's up for going on a camping trip, or concert or sporting event."
