Bullock laughs off dating rumors

SANDRA BULLOCK has brushed off false reports she's dating her THE PROPOSAL co-star RYAN REYNOLDS' best friend, insisting the only man in her life is her son.

The Oscar winner has been romantically linked to Reynolds' pal and business partner Jonathon Komack Martin, a Hollywood film producer.

But the actress insists Martin is actually an old friend - and not her latest love interest.

She tells GossipCop.com, "For over a decade now, I have been so lucky to have Jonathon and Ryan as my friends, and I agree with the reports that they are both very handsome and a great catch!

"But the only man who has stolen my heart is my son. And for now I wouldn't have it any other way!"

Bullock adopted Louis Bardo in 2010.
