Jennifer Aniston is taking her love of coffee to new heights after signing on to star in a new British Tv ad, in which she plays a caffeinated late-night cafe visitor.

In the new Sky Broadband commercial, the former Friends star portrays a woman struggling with a bad internet connection that forces her to work from a nearby coffee shop.

As the cups line up on her table, Aniston becomes more and more jumpy and alert, even swatting a fly in mid-air.

When a barista asks her if everything is Ok at home, the actress states: "Devastating. My internet is down again. Again."

The cafe employee advises her to sign up for Sky Broadband, prompting a happy Aniston to leave, yanking a door off its hinges as she exits.
