Marilyn Manson was a guest on the Howard Stern show earlier this morning and said he went to a party where No Doubt singer Gwen Stefani was at and claims that her husband and Bush frontman Gavin Rossdale made a pass at him. He also claims that he urinated on Gwen’s toilet seat at the party. Howard wondered why he would do such a thing. Marilyn said Gwen thought it was funny and didn’t kick him out of the party. He said he told her about it after he did it. Howard wanted to know how Gavin came on to him. Marilyn said he didn’t say anything to him, it was just a look he gave him. Marilyn said he doesn’t think Gavin is gay, he just thinks he likes the way he looks.
