FASHION insiders are abuzz with talk Katy Perry may make an appearance at Rosemount Australian Fashion Week next month.

The singer, who has just been announced as the new global face of ghd, will arrive in Sydney on May 3 ahead of her performance at the Entertainment Centre the following night.

With the hair-care brand sponsoring a bunch of designers, there's talk the star may grace a front row or two.

"Her schedule is quite intense but if she gets some free time she's considering dropping by," said a source.

One star who will attend the industry event is British '80s supermodel Yasmin Le Bon, who will join friend Gail Elliott at the model-turned-designer's Little Joe fashion show. Word is the 46-year-old wife of Duran Duran frontman Simon Le Bon, could also be hitting the catwalk.There's always a huge buzz as to whether an international star will grace the front rows at RAFW. Some years have delivered great talent such as Dita Von Teese and Mischa Barton, and others, well, haven't.

Fashion purists argue that it's not about the celebrities, but you can bet if someone like Perry shows up to a designer's show the global publicity will be absolutely priceless.
