According to an article at notifiradio.com Bob Bryar is out of the band.
“Looks like My Chemical Romance’s drummer is out of the band. According to a reliable source, who heard from drummer Bob Bryar’s family, an arguement of some sort ensued between Bryar and the rest of the band and Bob is out. A link to Bob’s twitter account on http://www.mychemicalromance.com has been disabled.”
Personally, I don’t think there’s any truth in it whatsoever, it’s just another rumor. Bob’s Twitter link has been disabled on the official site, but I believe this is just because his Twitter page was set to private and has probably now been deleted.
