Mika paid for promotional posters to be displayed near his ex-lover's house.

The 'We Are Golden' singer - who refuses to comment on speculation about his sexuality - was so devastated at being dumped shortly before he found fame with his debut hit 'Grace Kelly', he couldn't resist showing off in front of his former flame.

He said: "It happened three years ago, just before it all took off. I should never have got my heart broken. It was the first time in my life I realised it was something you can't control.

"I added £2,000 of my own money to the promotional budget to put the posters everywhere so the heartbreaker could not escape. I gave money to hammer them in one particular neighbourhood in London."

Despite his success, Mika insists he is not interested in partying too hard because he was so wild in his youth.

He added to Britain's Heat magazine: "I'd sneak out of my house at 3am to hang out with people who were too old. I used to go to this club every Monday, put on some guyliner, party it down. I always got caught, though.

"I was doing things I shouldn't have been doing. And I'm glad I did it then, because now I've stayed sane. I'm kind of over it. I don't see the point now."
