Aniston 'exhausted by John Mayer jaunt'

Jennifer Aniston has reportedly been suffering from exhaustion after touring with boyfriend John Mayer.

The actress visited four countries in 11 days and travelled an estimated 11,400 miles last month while following her musician lover on his recent world jaunt.

"It's been exhausting and exhilarating at the same time," an insider told In Touch "They're always on the go and that's why she's losing weight."

Doctor Richard Fleming, who specialises in cosmetic surgery, added: "Stress, travel and exhaustion can have a dramatic effect on people's faces even after a few weeks.

"She looks exhausted and drawn. It gives her a hungover look, even if she hasn't been drinking. Unfortunately, it has a greater effect because she's 39 and not 25."
