Another day, another piece of news to add to the Kristen Stewart cheating scandal saga: According to Gawker, gossip site Radar Online is claiming that scorned boyfriend Robert Pattinson is livid that Stewart has been shacking up at Welcome to the Rileys financier Giovanni Agnelli's pad post break-up, and is accusing her of sleeping with Agnelli in addition to her affair with Snow White and the Huntsman director Rupert Sanders. Allegedly, he's been expressing this anger by calling Agnelli "a lot." Oh RPattz, don't you know everyone has caller ID these days?

Something to note, however - fellow gossip site, Gossip Cop, is disputing Radar Online's story, accusing the site of making it up and posting their own round-up of KStew and RPattz news with multiple sources cited. These days, it really is hard to tell who you can trust anymore.

As for things that have been confirmed, Pattinson has been staying at his Water for Elephants co-star Reese Witherspoon's vacation home in Ojai, California since the split, and Sanders' estranged wife, Liberty Ross, has forbid the director from working on the Snow White and the Huntsman sequel.
