It’s hard to imagine what more we can see of Katy Perry, but the sexy singer may strip to her skivvies next month as she joins the Victoria’s Secret Angels in their annual lingerie fashion show.

The brunette singer is famous for her sassiness and will make a fitting edition to one of the most renowned lingerie fashion shows in the world. Upmarket underwear brand Victoria's Secret hold a runway parade annually, in which some of the top models in the business - previously including Heidi Klum, Alessandra Ambrosio and Miranda Kerr - don barely-there outfits in front of a large audience.

Katy is already starting to get nervous about matching up to the models' sculptured bodies on stage at the November 30 event, which is to be held in New York.

Perry, who is set to marry comedian Russell Brand in a lavish ceremony in India later this month, was reported to be feeling the pressure of going up against some the world's most beautiful bods - "I might need to up my game," she told ET's Kevin Frazier. "Maybe a couple of extra workouts so I can fit into some of those outfits."

Heidi Klum will not be walking in this year's show. The German supermodel, and wife of past performer Seal, announced in October that she was parting ways with Victoria's Secret after 13 years with the company.

Angels Miranda Kerr and Doutzen Kroes are both absent from the list of featured models for this year's show. Both Kerr and Kroes are pregnant - Kerr with husband Orlando Bloom and Kroes with fiance Sunnery James.

The Victoria's Secret Show will however feature a performance by Akon, and star the company's Angel models including Adriana Lima, Rosie Huntington-Whiteley, Candice Swanepoel, Chanel Iman and Erin Heatherton. Victoria's Secret Angel Adriana Lima is reported to return to the runway after taking a year off for the birth of her first child, Valentina with her husband, Real Madrid basketball player Marko Jaric.

The Brazilian beauty will walk in a 2 million dollars, diamond-encrusted Fantasy Bra designed by Italian jeweler Damiani, The New York Post reports. A sneak peek of the precious undergarment is due at the Victoria's Secret SoHo store on Wednesday, where Lima will model it under a Marilyn Monroe-style dress.
