Kristen Stewart

New reports claim the 'Twilight' actress went back to her married lover - who she was caught on camera kissing while she was still in a relationship with Robert Pattinson in July 2012 - once his divorce from Liberty Ross was finalized because she had "real feelings" for him.

According to America's OK! magazine, the 'Snow White and the Huntsman' director and the 23-year-old star's second chance at love was short-lived with Rupert abruptly calling things off after the first time they met up after his divorce.

The 42-year-old filmmaker's ex-wife - with whom he has children Tennyson and Skyla - is reportedly fuming over the revelation and the fact Kristen has never apologized to her.

A source said: "Liberty recently left a message for Kristen, suggesting she might as well sew a big letter 'A' on her chest, since she's never really apologized to the now divorced mum."

Meanwhile, it appears Robert has finally moved on from Kristen after their on-off romance petered out earlier this year.

The British-born star - who has since been linked to Elvis' granddaughter, Riley Keough - has just put the Los Angeles mansion the couple once shared on the market for £4.2million, after initially purchasing it in 2011 for £3.9million.
