Music star Simon Cowell has confessed he is envious of the success of popular US animated series 'The Simpsons' and says he wants to create a rival show.

Cowell, who earned an estimated $75 million in 2009, has revealed despite being a fan of the animated series, he is jealous of its worldwide success, reports fametastic.co.uk.

'Their appeal is broad and it makes a lot of money. You kind of hate them for making so much money. It makes me physically sick knowing how much money they have made over the years. Maybe I should start a cartoon one day,' he said.

The 50-year-old has previously made cameo appearances on the show but admits he only took part to preserve his youth.

'It's the best thing to get the call. You last forever and are young forever on that show, so I love it. The only reason for doing it is to look good and stay young forever,' he said.

The 'American Idol' and 'Britain's Got Talent' star recently also signed up to make another appearance on the cartoon, despite admitting his last appearance didn't go well.

'They obviously hated me as I had to do it over and over again.I could actually feel the rolling of eyeballs. It was like, 'after take 57 Simon could we have a little bit more reality?' It was painful,' he said.
