"Us Weekly" claims Kristen Stewart allegedly had a “steamy affair” with her Snow White and the Huntsman director Rupert Sanders.
A small photo featured on the cover seemingly shows Sanders — who is married to and has kids with Snow White actress Liberty Ross — wrapping his arms around Stewart in an embrace.
"Us" claims the two were photographed not long ago making out.
"People" magazine is also reporting a similar story.
However, Stewart and Pattinson attended Sunday’s Teen Choice Awards together.
