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 actress 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.
