Avril Lavigne has filed for divorce from estranged husband Deryck Whibley.

The 'Girlfriend' singer took action to officially end her three-year marriage to the Sum 41 star at a Los Angeles court last Friday (09.10.09), citing "irreconcilable differences".

Avril Lavigne was reportedly seen flirting with another man in the lead up to her split from husband Deryck Whibley.

The 'Girlfriend' singer - who announced she was separating from the Sum 41 rocker last week - spent a month partying on oil heir Brandon Davis' yacht in St. Tropez, South of France, and sources say the pair have grown very close.

Avril Lavigne has pledged to stay friends with her "amazing" estranged husband.

It was announced yesterday (17.09.09) that the 'Complicated' singer had ended her three-year marriage to Sum 41 rocker Deryck Whibley, but despite moving out of their Californian home, Avril insists she will see the 29-year-old musician regularly.

Avril Lavigne and Deryck Whibley have split.

Avril is said to have asked Deryck, who she wed three years ago, to move out of their Los Angeles mansion after calling time on their relationship.

Amy Winehouse wants to launch her own perfume. The troubled singer - who has publicly battled addictions to drink and drugs - and her father Mitch are keen to develop her trademark "smoky" look and put her name to a woman's fragrance.

A source said: "Mitch is keen to license Amy's name to a perfume house. He has been in talks with manufacturers and contacted PR firms for advice."
