Music mogul Simon Cowell has announced he will be revealing some big news in the near future and is feeling ''very positive'' about his life.

The 54-year-old X Factor judge posted a series of mysterious messages on his Twitter page yesterday promising fans some exciting news in the next few weeks.

He wrote: ''Excited to reveal some news in the next few weeks. Am feeling very positive right now. It's been hard work but nothing should be too easy.

''In life you can obsess on other people's failures or focus on your own mistakes and work hard to make sure you don't repeat them.

''But hard work and focus gives you a chance to turn a corner. And that's how I am feeling right now.''

Cowell was recently left red-faced on the social networking site when he called his most successful X Factor winner, Leona Lewis, Leonard by mistake.
