Dedicated followers of fashion
Justin Timberlake's eagerly anticipated collection of William Rast clothes has been shown at New York Fashion Week.
The former NSYNC member isn't the first A-lister to launch his own line - many celebs have cottoned onto capitalising on their image-making cred to become fashion's new powerhouse designers.
Here we take a look at some other stars with their own clothing lines.
:: Bono
The U2 frontman doesn't seem like the type to get that worked up about clothes - surely all he needs are his leather jackets and sunglasses? - but surprisingly he launched his own range in 2005.
Along with his wife Ali Hewson, Bono has been promoting the Edun line - clothing which is both eco-friendly and made in family-run factories in South America and Africa.
The Edun range (nude spelled backwards) includes jeans and camisoles, and is sold in selected shops in the US and the UK.
:: Sean "Diddy" Combs
The US rapper launched his clothing line Sean John in 1998, which has arguably become the most successful celebrity brand ever.
He sells "designer, urban and hip hop clothing" and was named the Best Menswear Designer by the prestigious Council of Fashion Designers in 2004.
:: Gwen Stefani
Gwen's clothing line, which goes by the name of LAMB (Love Angel Music Baby), features bikini tops, Rasta-inspired colours, low-slung trousers and funky handbags.
It was launched in 2003, and since then celebs including Nicole Richie, Paris Hilton and Halle Berry have been spotted strutting their stuff in the star's designs.
In 2005, the 38-year-old singer expanded her collection with the 2005 Harajuku Lovers line.
:: Kate Moss
Last year Kate designed a collection of clothes for TopShop. The 34-year-old supermodel launched the line by modelling one of her dresses in the window of the high street chain's Oxford Street store, sparking something of a press frenzy.
Hundreds of fans turned up to get their hands on Kate's clothes so shoppers were only allowed to buy five items each.
The catwalk queen's range includes clothes, shoes and accessories and her most recent addition was underwear.
:: Jennifer Lopez
Music diva and film star Jennifer Lopez added designer to her chain of monikers when she launched a clothing line called JLO by Jennifer Lopez in 2003.
The line has since ended but in 2005 she launched a new range called Sweetface. The 39-year-old's brand includes everything from fragrances, clothing and accessories to watches and shoes.
Late in 2007 the star - who gave birth to twins this year - launched a new juniors' line called JustSweet.
:: Milla Jovovich
The 32-year-old Russian model and actress partnered up with fellow model Carmen Hawk to create quirky fashion label Jovovich-Hawk in 2003.
They opened a showroom in the US in 2005 and items from the range, which has won high praise from fashion types, are now in many stores all over the world.
In November 2006, the Council of Fashion Designers of America (CFDA) and US Vogue even nominated Jovovich-Hawk for the CFDA/Vogue Fashion Fund Award.
The vintage-inspired clothing line has also got the thumbs up from the stars, and has been seen on A-listers like Heidi Klum, Natalie Portman and Kirsten Dunst.
:: Nicky Hilton
The younger sister of Paris Hilton launched her own tween-targeted label, Chick, in 2004, featuring eccentric, trendsetting pieces that Nicky said reflected her own style.
The 24-year-old named her new venture after her childhood nickname.
Last year she started her second line, aimed at a more mature audience with a higher budget, called Nicholai.
