pbr Katy Perry is busy spreading her love of sweets across Europe.br ppbr The singer is promoting her new track and third studio album, both called Teenage Dream.br ppbr At a gig in Germany Katy, 25, said: "The One of the Boys record was very fruit-based you know. I liked strawberries and cherries and things like that and now it's more candy-based.br ppbr "It's just fun and cute and I think there is something very kind of nostalgic about candy, because you have it when you are a kid, you have it when you are adult and you remember like your certain ones that you love."br ppbr "I like to make people feel a little nostalgic on the good times rather than the grumpy old aged times," she added.br ppbr The California Gurl star is engaged to comedian Russell Brand and has spoken of her desire to become a dual citizen after they get married.
