The reality show personality and former child actor was on the set of the televised entertainment news magazine when the seizure struck.
Luckily, Dr Drew Pinsky was sitting right next to him and administered care until paramedics arrived.
Coleman suffers from a congenital kidney disease requiring dialysis and suffered another seizure in January. In February 2010, a month before his most recent bout of illness, Coleman stormed off the set of the same show when asked by guest lawyer Lisa Bloom if he had attacked his wife, in the wake of his guilty plea to domestic violence charges.
