Rosie Huntington-Whiteley's Look Transformed by Nipple Action

Model seemed to have left her high beams on while strolling the streets in Los Angeles

Someone tell Rosie Huntington-Whiteley there's no need to use her high beams in the daytime.

The SoCal sun was shining, but the Transformers: Dark of the Moon star looked a little bit, er, chilly in West Hollywood today.

Huntington-Whiteley appears to have opted to go braless underneath her taupe sleeveless top, making it kinda, er, hard to keep one's attention on her pretty face or—the usual scene-stealer—her all-around great bod.

Then again, the blue-eyed beauty is no stranger to freeing her upper region from the constraints of an undergarment.

She posted a topless selfie photo to show off her raging sex appeal new jeans in February—but in that case she made sure to strategically place her arm at the perfect angle so that her nipples were covered.

Guess she's making up for lost time.
