One of the hardest working guys in showbiz is going to have to take it easy for a little while. Regis Philbin, 75 (can you believe that?), has scheduled open-heart surgery for later this week. Philbin made the announcement today on Live with Regis and Kelly, saying, “There’s some plaque in some arteries and I got to get it cleaned out.” Huh, sounds a bit oversimplified, but Philbin said that chest pains and shortness of breath led his doctors to this decision. He also expressed his concern, saying “Darn it, I don’t want to do it. Nobody wants to do it, I guess.” Friend of Philbin, David Letterman underwent a quadruple bypass back in 2000. His recovery is expected to take five weeks and perky co-host Ripa commented that she would dress as a nurse and give him a sponge bath during recovery. In the meantime, look for a cavalcade of guest hosts to fill the void on the chatfest.
