Gwen Stefani has admitted that her marriage to Bush singer Gavin Rossdale has been a saga with many ups and downs.

The No Doubt singer's husband was revealed to be the father of teen model Daisy Lowe in 2004, two years after the couple had wed. The model is the daughter of Kate Moss's friend Pearl Lowe, who is now married to Supergrass drummer Danny Goffey.

Speaking about her relationship with Rossdale, Stefani told The Observer: "I don't know. It's one of those mad love affairs that you can't live with and you can't live without, and you just keep going and going."

The singer had a baby called Kingston with the rocker in 2006. Speaking about their child, she added: "And time goes by and you get the rocky times and the intense love times, and then you get the reward of having the baby."

She added: "It's just this ongoing saga. I'm interested to see what's going to happen next, you know?"
