(NEWSER) – The Robert Pattinson-Kristen Stewart saga just gets messier, at least by Radar's reporting. The gossip site now says that Pattinson, who reportedly fled to Reese Witherspoon's side after news of Stewart's dalliance broke, is accusing Stewart of having an affair with the man she fled to: Giovanni Agnelli. She has apparently been staying at the producer's home (he worked with her on 2010's Welcome to the Rileys) since leaving the lovenest she and Pattinson shared.
"Rob knows Agnelli and has been calling him a lot since Kristen has been there," says a source. "He wants to know why Kristen is staying there... he is super angry now and has accused Giovanni of sleeping with Kristen too." But one source's description of Stewart's stay with Agnelli doesn't exactly paint a picture of sexy time: "She is crying her eyes out non-stop and does not want to communicate with anyone. Kristen hasn't showered or changed or washed her hair in several days. She is laying around in her T-shirt and shorts and eating ice cream."
