Russell Brand doesn’t care if Katy Perry embarrasses him in public.

The British funnyman insists he doesn’t mind his fiancee making up stories or revealing intimate details of their life - such as when she claimed he is obsessed with planning their wedding, or when she posted a picture of him in a wedding dress on twitter - because she is so “sweet”.

He said: “Katy’s tweeted pictures of me in a wedding dress. She makes up lies. It really amuses her, and when she gets home and shows me these things on the internet she’s so happy with herself. That’s the only thing that stops me from getting angry and going on a vengeful campaign - believe me, I’ve got photographs that would knock that wedding dress shot into orbit.

“She’s very sweet to me and really loving, which is why I can tolerate her planting rumours about me being Groomzilla and putting photos of me in a wedding dress on the internet. She’s really, really sweet.”

Russell - who has previously been treated for drug addiction - admits planning a bachelor party before his wedding will be difficult because he has given up so many of his vices.

He explained in an interview with heat magazine: “I don’t take drugs any more, I don’t drink. So what do you do? I can’t have sex with people on the stag night, so what’s the point? I might as well watch television!

“That’s the challenge for my best man, Nick - to make a stag night for a man who can’t have sex, do drugs or drink in any way.”

Russell and Katy - who started dating last September and got engaged two months later - are expected to marry in October.
