Now Jonathan, 27, is a huge star in the US after overcoming depression and having his life “saved” by Simon Cowell’s talent show.
The talented singer lost four stone in weight after turning his life around – and now looks totally different.
Jonathan finished second place in the sixth series of the ITV show with his singing partner Charlotte Jaconelli.
They were beaten to the prize by performing dog act Ashleigh and Pudsey.
Jonathan and Charlotte soon recorded their first album, Together, for Simon Cowell’s label Syco, and it reached No 5 in the British charts.
Thriving on the success, Jonathan ended up dropping from 20st to 16st.
He said: “I signed up with WeightWatchers last year, but I didn’t take it seriously until this April – now I’ve lost 4st.
“I never felt pressure to lose weight from people in the music industry but I wanted to do it for myself. I feel much better within myself and will keep going.
