Making alleged matters worse, a "super angry" Robert Pattinson has been phoning Agnelli "a lot" since Stewart became his house guest, mainly to accuse the Welcome to the Rileys financier of sleeping with Stewart as well.
Gossip Cop has accused Radar of making up both the Agnelli sleepover story and the subsequent affair accusation, citing multiple sources.
People magazine, meanwhile, says Stewart's sole confirmed lover Rupert Sanders has been estranged from wife Liberty Ross since he informed her of his affair.
Pattinson, who has also been shunning the spotlight since news of the tryst first broke, was reportedly spotted at a bar in Ojai, California, Friday night.
Patrons at the Deer Lodge, located not far from Reese Witherspoon's ranch where the Water for Elephants actor is known to be crashing, claim Pattinson was enjoying the atmosphere with some friends and "seemed in good spirits."
