Jennifer Aniston and John Mayer's love song

Nov. 4 -- It was another sweet date night for Jennifer Aniston and John Mayer.

The lovey-dovey duo hit singer-songwriter Ray LaMontagne's concert last night at the Wiltern Theater in Los Angeles.

"After the lights went down, they walked to their seats," an eyewitness tells me. "They were with two bodyguards and three other women."

It appeared that they had an entire block of tickets, because no one else was in their row, and three seats were left empty all night.

"They were hugging, but there wasn't any kissing," my source says.

"If you haven't heard Ray LaMontagne yet, you owe it to yourself to check him out," Mayer blogged on his official website earlier this month. "I've seen him twice in the past two weeks and I can't get over how powerful he is. He's so pure, it's arresting. People ask me all the time what artists I'm listening to, and what I think of certain singers or bands out there. I think Ray LaMontagne is as brilliant as any artist that has ever lived."

Also at last night's gig was Justin Timberlake. He, too, didn't take his seat until the lights went down.

No word if LaMontagne's A-list fans will return to the Wiltern on Sunday for another one of his shows.
