Shannen Doherty opens up about when she learned of exhusband Kurt Iswarienko's alleged affair on her 'Let's Be Clear' podcast. ET has reached out to Iswarienko for comment. The 'Beverly Hills, 90210' alum, who was first diagnosed with breast cancer in 2015, says she felt 'betrayed' by her now ex, shortly before undergoing brain surgery earlier this year. Speaking with ET's Rachel Smith on Wednesday, Shannen says recording the podcast has been 'cathartic,' as she navigates her cancer journey. The first episode of 'Let's Be Clear With Shannen Doherty' is streaming now on all major podcast platforms.
