She ended up receiving a painful 17 stitches in her leg following the incident, which took place hours after she performed at the MuchMusic Video Awards.

Despite her injury, Perry battled on and put in an impressive performance yesterday in a white latex dress and Chanel candy-striped peep-toe boots.

Writing on her Twitter page before her performance yesterday, she said: '17 stitches later... Don't make fun of my dance moves tomorrow. That's what got me here in the 1st place! Thanks for the souvenir Canada.

'Thinking about getting a candy cane walker made for this performance coming up... I will be expecting YOU to dance for me, okay?'
As well as preparing for the release of her new album, Teenage Dream, Perry is also trying to plan her wedding to Russell Brand, 35, who is currently promoting his new film Get Him To The Greek in Dublin.

The pair got engaged in India over the New Year and they are planning to wed in September - exactly a year after they started dating.
