Boy George knew about it too !!
Boy George described Rossdale as "very flirtatious and ambitious. When I was writing Take It Like A Man, Bush were well on their way to rock stardom and he appeared at my house to persuade me not to include him and Marilyn.
"I agreed to leave some stuff out but I wasn't prepared to lie. I don't think Marilyn has ever really got over Gavin."
Responding to Boy George's claims, Gavin previously said: "I wasn't dating Marilyn. We were, and still are, good friends. George thinks everyone is gay."


Hmm... this is interesting. It's literally a he-said, he-said situation. Gavin seems to be happily married to Gwen Stefani.
