Mayer 'jealous of Aniston's ex'

John Mayer is reportedly jealous of girlfriend Jennifer Aniston's ex.

The couple are rumoured to have argued during a romantic break in Mexico prior to the singer's European tour.

Mayer lost his temper after a member of staff revealed that Aniston had visited the location with former flame Vince Vaughn, according to the National Ledger.

He allegedly stormed off down the beach before the actress reassured him that her previous vacation was more than two years before and she now only had eyes for him.
