1980s singer Marilyn says he is pleased that Gavin Rossdale has told the truth about their relationship – but claims he did it for publicity.

The 47-year-old, real name Peter Robinson, said last year that he and the Bush singer had a five-year relationship.

Rossdale had always denied the claims until this week, when he told Details magazine that he had a “fear” about the relationship becoming public and called it a “part of growing up”.

Marilyn said he was “pleased” Rossdale had admitted the relationship, but added: “I find it sad that when I spoke out about what we had, I was labelled a tattle tale – and now Gavin is using it to promote himself.”

In 1995, Boy George claimed the pair began the affair when Rossdale was 17, before Bush hit the big time.

Last year, Marilyn said Rossdale had been the “love of my life”.

“I agreed to lie against every grain of my being,” he said. “We were together five years, but it felt like 40.”

Rossdale now reportedly has to explain the relationship to his wife Gwen Stefani.

She was said to be shocked in 2004 when a paternity test revealed him to be the father of model Daisy Lowe.
