It's official: Jennifer Aniston
is a John Mayer
groupie. After trekking with him to shows in Michigan
and St. Louis
this month alone, she put in another low-key appearance Sunday night in Irvine, Calif.
Early in the two-hour show – while Aniston looked on – Mayer prefaced a cover of Tom Petty's "Free Fallin' " with a bit of detail about his plans for the evening.
"Just like me, this song gets to sleep in its own bed tonight," he said, apparently happy to be home after a whirlwind tour of the Midwest.
But Mayer seemed to make a point of any overt references his romance with Aniston
, saying more than once that the night would be about "more music" and "less talk."
