Katy Perry (Bauer Griffin) Just when we thought Katy Perry was over her pink hair, she's dyed it back! The singer was spotted out last night with strawberry hair and a cute knit cap. She strolled around London with the updated 'do.

The singer is going to perform 2 nights at the O2 Arena in London this weekend, so she probably wanted fresh dye for the big concerts. She's so excited to rock out with her British fans: "Excited & honored to b able to perform TONIGHT & TOMORROW 2 Sold out shows @ the O2 arena in LONDON! I wanna tattoo a union jack on me face!" she tweeted.

The starlet has some other big news on the horizon: Her second fragrance is called Meow! She tweeted the announcement today, after lucky followers guessed the name correctly. "MOST of u guessed right! My next fragrance & bestie to Purr is MEOW! She's very sweet & inspired by that magical place, CANDYFORNIA! "
