Avril Lavigne says her latest clothing collection is her sexiest yet.

The 'What The Hell' singer launched her Abbey Dawn range in 2008 and says the newest designs are a lot more feminine than the ones before because she's starting to grow up.

She said: ''It's a little more geared toward an older age group. It's feminine, it's sexy, it's flattering, it's black, it's rock 'n' roll.

''I'm 27. I'm getting old.''

Earlier this year, signed a deal with JustFab.com to launch an accessories line for Abbey Dawn and she has said she's really proud of the collection, which consists of 12 shoe styles and five handbags.

She explained: ''Overall, the style of Abbey Dawn is rock 'n' roll, so you see a lot of spikes and skulls and black. They are bold pieces. They make a statement. They are a lot of fun.''

Kimora Lee Simmons, president and creative director of JustFab.com, added: ''Avril, I feel, is such a punk rock sweetheart. She really has a distinct look, feel, flair and style, and certain elements of that, speaking from a design standpoint, will cross over and resonate with our members.''
