Taylor Swift is the latest celebrity to appear in an advertisement for the Got Milk? campaign.

The country star poses with her guitar as she sports the notorious milky moustache to get kids and adults drinking more of the white stuff.

The young Grammy nominee admits she was overwhelmed to be asked to team up with the health promoting campaign.

"I've always seen the ads in the magazines and thought, 'If that could be me, I would be so lucky!'

"Also anything that promotes good health is something that I believe in," she tells OK! magazine.

The young starlet has been romantically linked to Joe Jonas.
