Zoe Saldana showed off her extremely thin frame while running errands in Sunset Boulevard in L.A.

The Avatar actress has always boasted a slim figure, but wearing skinny jeans and a small jumper only highlighted Zoe's thin frame.

Despite looking glum while out and about yesterday, Zoe apparently has a lot to smile about at the moment, with reports surfacing that she debuted her romance with Bradley Cooper two weeks ago at the Sundance Film Festival in Utah.

The pair have been spending an increasing amount of time together recently and they were even spotted leaving a house in the early hours. 

Do you think Zoe is too slim? Check out the pics in the gallery below.
