Either John Mayer has split from Jennifer Aniston or they have a very open relationship, intouchweekly.com reports.

The website says the musician was spotted on an intimate date with a beautiful blond woman at Marix Tex Mex Restaurant in Santa Monica last week. “They were obviously on a date,” a source tells In Touch. “He came in with her another time, too, and I’ve seen them out together.”

While the two keep their romance under wraps, the source says John couldn’t hold back his feelings for her when saying goodbye. “He gave her a long kiss before they left,” adds the insider. “John has been here six times in the last two weeks but never with Jen.”

Mayer, 31, and Aniston, 39, split last August after dating for several months, but found it difficult to go their separate ways. The two rekindled their romance in October and in early January, the couple was even seen vacationing together in Cabo San Lucas in Mexico.
