London, May 27 : Jennifer Aniston is so serious about new beau John Mayer that she's reportedly thinking about getting a tattoo to mark their love.
A source reveals that the former 'Friends' star is thinking about either adding a heart to the small one she already has on her stomach.
Mayer however has another idea - that both of them should get the letter 'J' done in a secret place.
"John also had the idea that they should both have a 'J' tattooed in a secret place as that is both their first initial," the Daily Express quoted a pal, as saying.
"Jennifer is really keen on the idea but is going to wait a few months."
For the moment however, the couple are having a "wild time".
"He said she's in great shape and her skin is like a baby's bottom, although she constantly refers to the age gap," the source added.
