Katy Perry wants to live in London with her fiance Russell Brand.

The 'California Gurls' singer loves the UK capital - where Russell lived before heading to the US to be with Katy - because it is such an exciting city.

She said: "I think I would probably go to London, and not just because of the fact I've got connections there, but because I like the constant evolution of the style and everything is so new.

"Sometimes I think I'd like to live in Japan but I don't know how I would get on there because I don't speak Japanese, I'd probably end up singing in the street with a little hat saying, 'Please support me.' "

Although Katy is keen to become an Anglophile she isn't sure if she could cope with the city's rainy weather.

In an interview on YouTube, Katy - who is from Santa Barbara, California - said: "I'd probably eat my words if I was living in London because I can't stand the weather, I'm such a sunshine girl. If the sun comes out I come out, if the sun doesn't come out you won't see me. I'm a California girl!"

Katy also lifted the lid on her wedding plans and revealed she isn't planning on having any crazy make-up when she and Russell tie the knot.

The 25-year-old singer - who is known for her figure-hugging latex outfits and love of unusual nail designs - said: "I'm kind of a nail aficionado and sometimes I'll have pictures of my cat on my nails and I had Oompa-Loompas on my nails when I had a Willy Wonka-themed birthday party. For my wedding I'm going to do what I call wedding nails which is basically traditional and pretty. Because you see those photos where you're holding each other's hands and I don't know if I'd like Oompa-Loompas on my nails while taking my photos. So I'm going to have wedding white nails."

Katy also revealed she thinks Russell, 35, will be a great father when they eventually have children.

She said: "We're excited to get married, of course. I think in marriage, when you're picking a partner, one of the things to keep in mind is would they be a good baby daddy and he'll be perfect."
