Despite rumors, Sandra Bullock‘s rep exclusively tells PEOPLE that the star is not married to boyfriend Bryan Randall.

“They are not married,” Bullock’s rep tells PEOPLE.

The denial follows a flurry of rumors claiming the two secretly tied the knot.

Bullock started dating Randall, a Los Angeles-based photographer, in the summer of 2015. “They started dating after Bryan photographed [Bullock’s son] Louis for his graduation,” a source told PEOPLE at the time.
