Katy Perry's fiancé, Russell Brand, has been MIA because he is so caught up with the Soccer World Cup.

The couple, who have such hectic schedules, got to spend a rare day off together, but Russell didn't want to go out because he had to watch England's crucial match against Slovenia.

Katy said: "It's funny because he's always there for me and we're always there for each other, but yesterday we had a day off – he had a day off as well because he's been busy promoting his movie (Get Him to the Greek) – and the game was on yesterday and everybody in England, everywhere, was quiet, no one is on the street. We were watching the game and I was like messing with him saying: 'Darling I really want to go outside.' And he was so caught, he was like: 'But the game, the game...' But I knew I wasn't gonna pull him away from that game. So I just took a nap."

She added that Russell is so obsessed with the World Cup, that he is up late every night reading about the latest news on all the teams.

"Everything is about football right now,” she said. "It's like; when I was with him last night he was up late watching football. And he was online reading all about it and it's like: 'How much can you read?'"

Get into the spirit Katy, KE NAKO!
