Now Jonathan, 27, is a huge star in the US after overcoming depression and having his life โsavedโ by Simon Cowellโs talent show.
The talented singer lost four stone in weight after turning his life around โ 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 Cowellโs label Syco, andย it reached Noโ5 in the British charts.
Thriving on the success, Jonathan ended up dropping from 20st to 16st.
He said: โI signed up withย WeightWatchers last year, but I didnโt take it seriously until this April โ now Iโve lost 4st.
โI 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.
