The screening of 'This Must Be The Place' at Cannes

Singer Gwen Stefani arrives on the red carpet for the screening of the film "This Must Be The Place", in competition at the 64th Cannes Film Festival May 20, 2011.

Gwen Stefani scared of her parents

Gwen Stefani is still petrified of her parents.

The 39-year-old singer - who has sons Kingston, three, and one-year-old Zuma with husband Gavin Rossdale - claims the only reason she has never gone off the rails is because she is so worried about what her mother and father, Patti and Dennis, would say.

She said: "I was thinking today when I was driving, 'How am I going to make sure that Kingston never does anything bad and doesn't get arrested?' I was thinking, 'How did I stay out of trouble?' And I know it's just because my parents are so strict. I mean, I'm still scared of them!"

Gwen says being a mother is the most important part of her life, but is aware her children's upbringing is totally different from her own.

She told America's Glamour magazine: "I grew up in a normal family. The other evening, at the end of the night, I was there with Kingston putting him to bed, reading all his books, getting his diaper on and putting him in his crib. Then I got Zuma, nursed him, put him to sleep. Then I went to a Hollywood party! It is extremely different from how my parents raised me.

"I've always worked really hard, and the hardest thing I've ever done is have kids! Everything from getting up in the morning, to trying to be consistent, to trying to have the right feelings. But, of course, the rewards are great."

Gavin Rossdale romanced man?

Singers Gwen Stefani and Gavin Rossdale pose as they arrive at the 2009 Vanity Fair Oscar Party in West Hollywood, California February 22, 2009.

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."

In 1995, singer Boy George - a close friend of Marilyn - alleged Gavin, 43, and Marilyn had had an affair in his autobiography 'Take It Like A Man' but both men denied the claims.

However, Marilyn - real name Peter Robinson - insists he lied in order to protect the 'Swallowed' singer's burgeoning career.

The 'Calling Your Name' star added to In Touch Weekly magazine: "He was just becoming successful in America. I agreed to lie against every grain of my being."

Responding to Boy George's claims, Gavin previously said: "I wasn't dating Marilyn. We were, and still are, good friends. George thinks everyone is gay."

Boy George - real name George O'Dowd - insisted the story was true and alleged that Gavin had begged him not to include details of his gay romance in his book.

George recalled: "When I was writing 'Take It Like A Man', Bush were well on their way to rock stardom and he appeared at my house to persuade me not to include him and Marilyn.

"I agreed to leave some stuff out but I wasn't prepared to lie. I don't think Marilyn has ever really got over Gavin."
