Katy Perry's special-edition Barbie doll "sums up" her unique "personal style".

The American songstress has had an impressive one-of-a-kind toy made by Mattel.

The doll sports a replica of the stunning cupcake-covered dress from Katy's hugely successful California Dreams world tour wardrobe. The candy-coloured dress is teamed with pink and purple heeled sandals with Swarovski crystal-encrusted fishnet tights.

The doll is completed with an electric blue wig - identical to the one Perry wore with her famous dress during the series of shows.

The intricately designed doll is testament to Perry's unique style.

"We hand-painted all the details and applied the crystals here in our design studio," Peter Helenek, VP of design for Barbie at Mattel Inc., told WWD. "They create a look that sums up Katy and her personal style."

Nicki Minaj also has a new Barbie. The rapper's replica doll features a long baby pink wig, complete with an impressively large rosy tulle dress and matching pink ankle boots.

Minja's doll comes completed with diamante cuffs and a Barbie necklace. Helenek says the attention to detail was paramount when creating the one-off collector's items.

"There are fans out there who look specifically [at the] shoes when buying [Barbies]," he revealed.

The dolls are on sale at Charitybuzz.com today. All proceeds will benefit Project Angel Food, which is a Los Angeles-based charity that delivers free meals to those with life-threatening illnesses.
