She had a devastating split from husband Jesse James in 2010 after learning of his serial adultery.
But Sandra Bullock showed she may be moving on when she was spotted stepping out with a mystery man.
Bullock and the man in question were seen attending a private party, with her companion proving to be quite the gentleman and opening the actress�s car door for her once they arrived.
The 47-year-old showed off a sheepish smile after clocking the cameras on her, but her attention did not stray from the gentleman for long.
They arrived at the Los Angeles location in the male�s white Porsche, and were spotted chatting to a fellow guest before they made their away inside.
The Extremely Loud and Incredibly Close actress wore a flirty grey leopard print dress for her day out, which she teamed with some black ballet pumps and a pair of aviator sunglasses.

Meanwhile her companion looked dashing in a checked jacket, cream trousers, white polo shirt and a navy baseball cap.
The actress recently denied claims that she was romantically involved with Ryan Reynolds, her co-star in The Proposal, last year.
A representative for the Miss Congeniality actress called the accusations �entirely fabricated�.
Bullock said of her 2010 marriage split: 'I was perfectly content to be permanently broken.
'I honestly didn't think I was in a place where I wanted to work or wanted to step out of where I was. I wasn't prepared.'
Bullock said she was persuaded to return to acting by director Stephen Daldry who wanted her to appear opposite Tom Hanks in drama Extremely Loud and Incredibly Close.
Earlier this month it was announced that the film has been nominated for Best Picture at the Oscars.
