Robert Pattinson on Friday night moved out of the home he shared with girlfriend Kristen Stewart, hours after her affair with a married English film director was made public.

The couple, who play on-screen lovers in the hugely popular Twilight saga, had come under immense strain after intimate pictures of Stewart, 22, and Rupert Sanders, 41, a father of two, were revealed on Wednesday.

In a desperate attempt to save their three-year relationship, Stewart, who was pictured on Friday looking tearful, made a public statement of remorse describing her behaviour as a “momentary indiscretion”.

But it appears Pattinson, 26, is not prepared to forgive her and the relationship is over. US magazine People revealed he has now left the Los Angeles home they shared.

A source quoted by the magazine said the actor, who grew up in Barnes, south west London, was “heartbroken and angry”, adding: “I’m not sure they’ll be able to recover from this.”

Stewart has faced a Twitter backlash from thousands of Twilight fans, some of whom have said she should die.

She met Sanders after he cast her in the lead role in his film Snow White and the Huntsman.

Sanders’s wife, the British model Liberty Ross, 33, played Stewart’s on-screen mother.

Gallingly Ross had been full of praise for Stewart. She told an interviewer at the London premiere in May that she “was my number one choice” for the role.

“I think there is no better Snow White,” she added. “She is great. She’s got something very transfixing about her.” According to US website Radar Online, Stewart, will now “do the decent thing” and write a private letter apologising to Ross.

A source said: “Kristen didn’t feel it was appropriate to issue a public apology to Liberty once the story of her affair with Rupert broke.”

The source added: “Kristen feels she made a terribly naive mistake and will do anything to make amends. The fact that Liberty and Rupert have two kids has now dawned on her and she feels awful for what she did.”

The full photographs were due to be published on Saturday by Us Weekly. They show the pair kissing and cuddling in her car in Los Angeles, with a witness describing them as “making out” like teenagers.

Pictures have also since emerged of Stewart and Sanders enjoying a meal out together in Berlin while promoting Snow White and the Huntsman.
