Miley Cyrus sunglasses singer shorts cafe

Hit her with your best shot! Miley Cyrus seemed to be going through some mood swings as she met a friend at a New York Bagel & Café in Los Angeles Wednesday.

The "Party in the U.S.A." singer looked super toned in her fave Pat Benatar '81 tour tee, tiny denim cutoffs, black flats and a spiky leopard print bag. But despite how fab she looked, she kept fluctuating between huge grins and angry scowls in a span of just a few minutes.

Miley also showed off the anchor tattoo she got on her right wrist during her Gyspy Heart tour this past spring. That makes a reported nine tats for the 18-year-old singer/actress.

Maybe that Gatorade will calm her down? After all ... the girl can't be a heartbreaker with a frown!
