(entertainmentwise.com) - John Mayer's
rock and roll lifestyle seems to be taking its toll on Jennifer Aniston's
appearance.
The Friends actress has been following her
boyfriend around, but playing groupie is a tiring job. In eleven days during July,
she logged nearly 11,400 miles to be with John around seven cities in four
countries while he embarked on his tour.
But the long days and night are taking their toll on Jen. A friend explains to In
Touch: "Jennifer's lost a few pounds since she started dating John.
It's been exhausting and exhilarating at the same time. They're always on
the go and that's why she's losing weight."
Cosmetic surgeon, Doctor Richard Fleming, also notes Jennifer's hectic schedule
is damaging her youthful looks: "Stress, travel and exhaustion can have a
dramatic effect on people's faces even after a few weeks.
"She looks exhausted and drawn," he adds to In Touch. "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."
