Katy Perry sad without Russell

US star Katy Perry misses her English boyfriend Russell Brand when she's in the UK and he's not.

Katy Perry gets "sad" when she is in England without Russell Brand.

The 'Teenage Dream' singer – who got engaged to the British comedian last December after a whirlwind three-month romance – admitted while she has a fondness for "anything British" she misses her fiance when he's the other side of the Atlantic.

She explained: "I'm very fond of London and England in general. I'm dating an English boy. I have a lot of fondness of anything British. I was incredibly happy just eating a big bowl of baked beans earlier – I was like licking the bowl. It's kinda sad though when I'm here and Russell's not.

"I love the frankness of the people, I love the tradition. I love the general ambience. When I get married I think I'm going to get my Britishness on me. I'll be like 'I love the Queen, I know all about tea.' "

The brunette beauty revealed while she is trying to "mature as a person", she is still as "crazy" as she has always been, and enjoys laughing at things that are considered wrong.

She added to website MSN.com: "It's still me underneath all this. I tried to stay as true to myself as possible – I think that resonates with fans of my music. I'm maturing as a person but I'm still as cuckoo and crazy as I've always been.

"Irony and sarcasm and things that could be considered wrong make me laugh. Crossing the line is definitely healthy."

The 25-year-old star recently admitted she plans to apply for British citizenship when she gets married.

She said: "When I get married next month, one of the first things I'll do is apply for dual citizenship.

"I'm not too sure if I have to take a test as I've not had time to look into it. But England is like my second home."
