Funnyman Robin Williams will undergo heart surgery after he was admitted Monday to at a South Florida hospital because the actor complained of shortness of breath, his publicist said.
A statement from Williams' representative, Diane Rosen, said the actor will have "to undergo surgery for an aortic valve replacement" and will postpone his comedy tour until the fall, the Associated Press reported.
"I'm so touched by everyone's support and well wishes," Williams said in a statement. "This tour has been amazing fun and I can't wait to get back out on the road after a little tune-up."
The 57-year old comedian complained of shortness of breath and canceled four performances of his one-man show "Weapons of Self Destruction" after doctors first evaluated him and recommended a week of rest.
The "Good Will Hunting" actor has been on an 80-city tour since September and has been to 11 cities over the past three weeks.
Williams rose to stardom with his role in the 1978 television series "Mork & Mindy" and is known for playing eccentric characters.
