John Mayer has been photographed sitting in a hot tub with another woman while on a Mexican retreat. Should Jennifer Aniston be worried?

The rocker, who is dating the Friends actress, has not been cheating on his girlfriend though claims a source close to Mayer.

The insider explains to Us magazine: "The woman in the photos is one of the wives of his band members."

The source goes on to reveal that Mayer went to Cabo San Lucas with his band "to take a break from the tour. It was a reward for them to get away and his way of saying thanks for all their hard work."

Another source adds: "There is nobody on the trip he could possibly hook up with and definitely not the woman in the photos or any of the women there."

Glad that’s cleared up, we wouldn’t want Jennifer facing another Angelina Jolie type temptress.
