Gwen Stefani is worried about taking her two sons on tour with No Doubt. The singer - who raises nine-month-old Zuma and Kingston, three, with her husband Gavin Rossdale - is concerned about how her bandmates will cope with her growing entourage.

She said: "Before, when I was with the guys, I didn't have any kids. That's like, whoa, a huge deal. They dynamic of the band is different. It has to be."

Gavin Rossdale had a five-year relationship with a male pop star. The former Bush singer - who has two sons with wife Gwen Stefani and a daughter from a previous relationship - allegedly had a long romance with androgynous British singer Marilyn in the 80s.

Marilyn, 46, said: "He was the love of my life. We were together five years, but it felt like 40."

Kate Hudson celebrated turning 30 with a star-studded bash at the weekend. The "Bride Wars" actress celebrated her landmark birthday with a host of famous faces including Demi Moore and her husband Ashton Kutcher, Justin Timberlake, Matthew McConaughey, Tobey Maguire, Jessica Alba and her husband Cash Warren, Gwen Stefani, Eva Mendes, Gwyneth Paltrow and husband Chris Martin, Adam Sandler, Zach Braff and Cher.

A source said: "Kate was elated, dancing all night, having the time of her life - and she looked amazing in a very sexy little dress and Christian Louboutin heels.

Gwen Stefani stole her son Zuma's name from her No Doubt bandmate. The "Wind It Up" singer - who has another son Kingston James McGregor, two, with her husband Gavin Rossdale - wanted a "quirky" name for her six-month-old child and got the idea of Zuma from her bandmate Tom Dumont's wife Mieke.

She said: "I kind of stole it from him. I didn't steal it, I mean his wife didn't want it. It was just one of those things that just happened. I just wanted Zuma to have a little bit of a quirky name."

Gavin Rossdale and Gwen Stefani bathe together - to avoid wasting water. Gavin - who has sons Kingston, two, and six-month-old Zuma with his wife Gwen - insists sharing a bathtub with Gwen is a good way to help the environment.

He said: "All families should bathe together. It's the least they could do!"
