Katy Perry says she is enjoying the opportunity to experiment with her hair colour and style but joked that she may have shave her head in the future as a result.
The 'Teenage Dream' singer unveiled a short blond bob recently after sporting long dark brown hair for much of her pop career.
"I'm having fun with my hair colour because I was black-haired for 10 years," Katy explained to E! Online. "That was a long time, so I just decided to change things up, try new things and see what worked.
"Who knows?" Katy teased. "I'll probably have to shave my head one day because of all of it."
Katy was seen sporting her new hair last weekend (10th December) when she appeared as guest host on Saturday Night Live alongside musical guest Robyn and guest actors Alec Baldwin and Kristen Wiig.
Katy Perry concluded her 122-date 'California Dreams' tour at the end of November and has since suggested she will take some time off before starting work on her third studio album.
