Jennifer Aniston and John Mayer are said to be driving their friends to distraction with their love-sick antics.

According to a report, the pair have already given each other pet names.

John has apparently taken to calling his girl “Tushie” on account of her squeezable rear, whilst the singer has earned the nickname “Mayo” because of his fondness for mayonnaise sandwiches.

Feeling queazy yet? Just wait until you hear which ringtones the loved-up couple have supposedly chosen for each other.

"When she calls, 'Pretty Woman' plays," a source tells Star. 

"And his hit, 'Gravity', plays when he calls her.  It's adorable, but it drives their friends crazy!"
