Jennifer Aniston is looking well on her three-month relationship with John Mayer.

The former Friends actress – who is not normally known for her revealing outfits - was happy to show off her new super-toned figure as she visited a pal in Beverly Hills this week.

It's been reported that Jen has been giving herself something of an image overhaul since hooking up with the younger singer.

As well as stocking up on sexy new outfits, it's claimed the 39-year-old has been splashing out $20,000-a-month on beauty treatments.

Looks like money well spent...
