Courtney Love’s war on Gwen Stefani just got a lot more personal: Love claimed on Howard Stern that she had an eight-month affair with Gavin Rossdale while he was married to Gwen Stefani. “He was such an Adonis in his day!” she said of the former Bush front man. “He got good in bed... something happened. Maybe Gwen taught him." Love says Stefani knew of the affair.
