Gavin Rossdale still wearing wedding ring two months after split

Rocker Gavin Rossdale is clinging on to the embers of his broken marriage by refusing to take his wedding ring off.

Amid unconfirmed rumours suggesting the Bush frontman cheated on his wife Gwen Stefani with their children's nanny, Rossdale was spotted out and about in North Hollywood, Los Angeles on Thursday (12Nov15) - and he was still wearing his wedding band.

He and Stefani announced their shock split in August (15) and the No Doubt singer has since embarked on a new romance with her fellow The Voice judge Blake Shelton.

Gavin and Gwen were married for 13 years.

New reports suggest his infidelity led to the end of the union - sources tell Us Weekly Rossdale and the family nanny, Mindy Mann, had a three-year affair, which Stefani discovered in February (15).

The source tells the publication, "She was mortified, livid, and embarrassed."

Representatives for the couple have yet to comment in the infidelity rumours, but mum-of-three Gwen alluded to the family drama during an interview with KIIS FM's JoJo Wright on Monday (09Nov15), stating, "Everybody knows that my life blew up last February. I'd just been dealing with that. Unexpected. I was going along thinking that was going to be the rest of my life and it's not. I don't know what happened."
