Kristen Stewart is reportedly "inseparable" from Robert Pattinson's best friend after "flirting" with him for a few weeks.
Kristen and Robert's relationship was rocked when the beauty admitted having an affair with married Snow White and the Huntsman director Rupert Sanders and they are thought to be separated at the moment.
The Twilight actress has reportedly turned her attention to Robert's best pal, British singer Marcus Foster, while Robert has been away filming his latest movie in Australia.
"Ever since Kristen met up with Marcus at a friend's house party in LA a few weeks ago, it seems as if she's been flirting with him in a bid to get over Rob after being so upset and wound up by the hurtful way it ended," a source told Heat magazine.
"Marcus initially blew Kristen off, insisting she was a 'mess' and said he'd never betray Rob, but it seems that over the past few weeks they have grown closer and are now impractically inseparable."
Kristen is said to have been rocked by revelations that on-off boyfriend Robert can't forgive her for her betrayal - with the pair reportedly set for "crisis talks" now he has returned from Down Under.
The 22-year-old star has allegedly been seeking reassurance from Marcus, 26.
"It seems Kristen's always had a secret crush on Marcus. There were rumours last week that she flirted with Patrick Schwarzenegger at a party she was at with Taylor Lautner, but she may have done this intentionally to divert attention away from her and Marcus," the insider added.
"He is about to leave LA for the next leg of his US tour and Kristen is saying she doesn't know how she'll cope. He's become her best friend over the past few weeks."
