Rupert Sanders has called his affair with Kristen Stewart a "momentary lapse".
The married Snow White and the Huntsman director had an affair with the 26-year-old actress - who was dating Robert Pattinson at the time - on the set of the 2012 movie but he has now branded their dalliance as a "mistake".

He told the Metro newspaper: "You never know what's coming in life. Around every corner, there's something unexpected, and that's life. You just have to brush yourself off and continue moving forward the best you can. Everyone makes mistakes."
"I am bound to make more mistakes, and I wouldn't expect my life to be exciting if I didn't. If you took people off the table for a momentary lapse, there would be no one making art."
