Gavin Rossdale finds marriage "challenging." The former Bush singer says he sometimes feels like "an appendage" because of the publicity his wife Gwen Stefani attracts - and hates being described as her "rocker hubby."

Gavin wrote on his MySpace page: "It's been a tough few years for me because I've been lost in how to define myself in the present tense. With that glare of the publicity on us, how can I not feel like an appendage at times?"

Mark Ronson is dating Gavin Rossdale's teenage daughter.

The 32-year-old producer was instantly smitten with Daisy Lowe - who only learned the Bush singer, who had been her godfather, was in fact her biological father four years ago - when they were introduced through mutual friend Sean Lennon and he has put all his efforts into wooing the brunette beauty over recent months.
