OMG, what happened to Joo Ji Hoon?

Just saw this in Popseoul:

Prince Shin of the K-drama Princess Hours doesn't look like much of a royalty these days. He looked like a dad, gaining pounds like that. He's stick thin during the Princess Hours days. Must be the 'rehab' and being away from the limelight.

I liked JJH despite his recent drug scandal. In all fairness to him, he's got spunk and he's a very good actor. =)
