Katy Perry's love affair with Perth fashion label Wheels & Dollbaby continued during her recent Aussie visit.

During her many press commitments promoting her film Katy Perry: Part of Me, the pop star wore a number of items courtesy of the brand, run by founder and head designer Melanie Greensmith.

The Teenage Dream singer managed to get her hands on some of Wheels' Spring Summer 2012 collection, including the Uptown Girl Dress and Butterfield 8 Sweater, before it hits stores next month.

But Perry isn't a newcomer to the label - last year, she gave tickets and invited the entire Wheels & Dollbaby crew backstage at her California Dreams concert in Sydney.

"She's been wearing Wheels since before she hit the big time, so it's great she can have any brand in the world but chooses us," Greensmith said.
