WHAT KATY KNOWS

In the wake of shocking sexual assault allegations against Russell Brand, his ex-wife Katy Perry is telling all

- Russell Brand

She’s sobbing uncontrollably. In a raw scene from her 2012 documentary, Katy Perry: Part of Me, Katy Perry breaks down backstage in São Paulo, Brazil, on Dec. 31, 2011 — moments after receiving a text from her then-husband, Russell Brand, saying he was divorcing her. At the time, she blamed her grueling tour schedule for the failure of the marriage. “I felt a lot of responsibility for it ending,” Katy told Vogue a year later before hinting at the shocking truth about their divorce. “But then I found out the real truth, which I can’t necessarily disclose because I keep it locked in my safe for a rainy day.”

Others haven’t guarded what they allegedly know about Russell so closely. On Sept. 16, four women accused the comedian of sexually assaulting and abusing them between 2006 and 2013 — including the 14 months he was married to Katy, 38. “It’s far worse than anyone knows,” an insider says of the women’s claims. “Katy has no idea what really happened, but she knows how Russell treated her — and she’s telling friends he was a monster.”

The comedian vehemently denies the four women’s allegations, but he acknowledges he was “very, very promiscuous.”
