Has Sandra Bullock finally found her rebound man in Brett Ratner?

A new story in In Touch mag claims that the Oscar winning actress, 47, and the director-producer, 42, having been hooking up -- and recently packed on the PDA at a party following the 2012 Academy Awards.

Alas, this particular story is extremely false and incredibly fake-- just ask Bullock and Ratner!

In a joint statement, the Blind Side star and Tower Heist director tell Us Weekly: "We think that it's incredibly sad that in these times, this magazine would resort to complete fabrication, solely for financial gain. There is not a shred of accuracy in their story. We have not seen nor spoken to each for over a decade. We both had a great time after the Oscars, just not with each other."

Single mom to son Louis, 2, Bullock hasn't seriously dated since she and husband Jesse James divorced in 2010.
