The singer, whose hits include Sk8er Boi and Complicated, wrote on her website: "We have been friends since I was 17, started dating when I was 19, and married when I was 21."

"I admire Deryck and have a great amount of respect for him.

"He is the most amazing person I know and I love him with all my heart."

Songs from the singer's as-yet-untitled fourth album, due out in November, have been produced by her husband.

Sum 41's last album, 2007's Underclass Hero, reached number seven in the US.

Amy Winehouse launches St Lucia residency bid

Amy Winehouse has supposedly filed a residency application to live in St Lucia permanently.

The 'Rehab' singer has spent much of 2009 on holiday on the island, and is now looking to settle there full-time, claims the News Of The World.

The newspaper quoted an anonymous St Lucia official as saying that authorities had received a residency application which was in the process off being assessed.

"We are aware of Amy wanting to live here on a permanent basis," they are quoted as saying. "We have received an application and are looking into it."

The jazz-pop musician would stand to make large tax savings if she were to live on the Caribbean island as oppose to in the UK.

Amy Winehouse had been set to play her first UK gig of 2009 last month at the London Shepherd's Bush Empire, although the show was pulled without a reason being given.

Katy Perry takes action against Katie Perry

Representatives for Katy Perry are attempting to prevent an Australian fashion designer from using the brand name Katie Perry to represent her clothing line, even though it is the designer's birth name.

The pop star's record label, EMI, sent a cease-and-desist order to the designer, who recently opened an outlet in Sydney, Australia. They claim that the names are too "similar", and that Katy Perry's brand name must be protected, reports Billboard.

The designer was born Katie Jane Perry, but occasionally uses the name Katie Howell.

The American singer's tune 'I Kissed A Girl' hit the top of the Australian charts in 2008, and she is set to embark on a tour down under this August.
