It's what we saw when Robbie left for the night that's troubling us - namely the mysterious substance he popped into his mouth on his way through Hyde's parking lot! Could Rehabbin' Robbie be relapsing already? Let's hope he just came down with a headache inside the club - preferably from the DJ blasting "Lovelight" too loud!
