Jennifer Aniston has reportedly been giving her wardrobe a makeover since hooking up with John Mayer.

The former Friends star – who, it has to be said, isn’t known for her daring dress sense - is supposedly spending her free time stocking up on sexy new outfits.

"Before she hooked up with John Mayer, Jennifer was 'blah' in beige," says a source.

"Now she is the sexy lady in red!"

Her recent purchases are said to include a made-to-order cocktail dress from exclusive West Hollywood boutique Noodle Stories.

Jen is in the midst of something of an image overhaul, if recent reports are to be believed.

It was previously claimed that she started splashing out $20,000-a-month on beauty treatments after getting together with boy-toy, John.
