I bet all the singers out there wish that they could have hot groupie’s like Jennifer Aniston at their concerts!

Jennifer arrived at one of her boyfriend, John Mayer’s concerts in London to watch him sing….

During that two-hour set — which included “Why Georgia” — Mayer made some jokes specially targeted for the British audience, sprinkling his remarks with such beer-y references as “cheers” “have a pint.”

At one point, he said, enigmatically, that “every relationship someone steps into might some how shake you up a bit. So I’m gonna take my time a little bit.”

Fans outside the gig said they had seen Aniston sitting in an upper level, playing with her hair watching the singer, and she and Mayer were seen leaving around 11:30.

They have such a cute love…and by these pictures you can tell she is quite smitten with him.
