Enjoying an evening of live classic rock, Jennifer Aniston and Courteney Cox were spotted at the Fleetwood Mac concert in Los Angeles last night (May 28).

The former “Friends” costars were joined by Cox’s husband David Arquette as they left the Staples Center following the gig.

And whether tabloid rumors are to be believed, it sounds like Miss Aniston is thinking about rekindling her romance with ex-boyfriend John Mayer yet again, as she’s allegedly been making late-night drunken phone calls to the “Gravity” stud.

An inside source told press, “[He] wasn’t calling her or texting her.  But, as she got lonelier and the shoot

for her new movie wore on, she started reaching out to him, sometimes very late at night and sometimes after a few too many glasses of wine.”

Unfortunately, Jen isn’t getting the green light from Courteney.  “Courteney is the biggest objector to a John reunion.  They never got along and Courteney is someone who has always told Jennifer she’s just too good for John.  Jennifer’s friends do not like John Mayer. But Jen, as always, acts from the heart, and whether she loses a couple of friends in the course of getting back together with John, next so be it.”
