His rep actually contacted TMZ, but was really ambiguous with the truth, they said;
In all honesty, its really not surprising. all of the JS crew get PAID to get drunk, and the situation can be paid between 15,000 and 50,000 whenever he makes an appearance at a club. All this partying and doing it constantly must really have taken it out of him, hopefully he gets better soon!
We wish him all the luck in the world!
