Love said the pair enjoyed an eight-month romance and that Stefani knew about the affair.

The widow of Nirvana frontman Kurt Cobain made the claims in an interview on The Howard Stern Show on Sirius XM Radio on Monday (April 26).

"Everyone gave me so much shit because Gavin sounded like a lot like Kurt...." Love said.

"But man, he was such an Adonis in his day! He got good in bed ... something happened. Maybe Gwen taught him, for all I know."

Asked whether she was implying that Stefani knew about the relationship, Love replied: "Yes. She does know."

According to Us Weekly, Stern the asked: "You mean he was having sex with you while he was with her?"

"Everyone ... yeah ... and a few other people," Love said. "We didn't have a lot of pressure on each other, but we did like each other quite a bit."

Stefani and Rossdale married in 2002 and have two children together.

Love is currently promoting Hole’s new album, ‘Nobody’s Daughter’, which is out now.
