We spotted Miley Cyrus flashing her flat stomach and toned body yesterday after she left a gym in West Hollywood. She wore tight black work-out pants, a gray tank top, and lace bra.

Not too long ago the singer/actress received some flak for putting on a few pounds, but these photos show her looking very slim and trim.

Last week she tweeted a photo of a ring on her left hand, causing speculation that she was engaged to Liam Hemsworth. The rumors were untrue.

She stars in the upcoming film "LOL" opposite Demi Moore about a 17 year old who rebounds from a break-up by attempting to seduce her ex-boyfriend's best friend and experimenting with drugs and sex.
