Zoe Saldana was spotted shopping in Los Angeles yesterday, but looked slightly glum and failed to raise a smile for the cameras.

The Columbiana actress looked chic in electric blue jeans and a plain white tee, as she ran errands around Silverlake. Zoe has been plagued with rumours recently that she is dating The Hangover actor Bradley Cooper, just months after she announced her split from fiance Keith Britton.

A source came forward to allege that Zoe is "totally dating" Bradley and even claimed that she had been introduced to his parents. 

The two have been working on a film together and were spotted kissing for scenes that will appear in the flick, but Zoe's rep has denied that their romance has blossomed off set. 

Check out the pics of Zoe in the gallery below.
