Reports Comedian Robin Williams has been admitted to a Miami, Florida hospital to be treated for heart issues, according to new reports.

The 57-year-old star sparked fears for his health on Wednesday (04Mar09), when he was ordered by doctors to take a week of rest after complaining of shortness of breath.

The news prompted the actor, who was scheduled to perform his one-man comedy show Weapons of Self-Destruction at various venues across Florida this week (begs02Mar09), to cancel gigs lined-up until Monday (09Mar09) to recuperate.

A statement released by the star's representatives said: "Williams was experiencing shortness of breath and is currently being evaluated by doctors who are recommending a week of rest."

New reports suggest Williams' health concerns are far more severe. The Miami Herald alleges the star checked into an Intensive Care Unit to seek treatment for a heart problem.

And Williams' publicist, Mara Buxbaum, has refused to comment on the new claims, telling WENN, "This is the latest news and remains accurate. As soon as we have further info, we will be sure to inform you."

Williams has been on the Broadway-bound 80-city tour since September (08) and has played shows in 11 cities over the past three weeks. No further comment had been issued by his representatives as WENN went to press. (JMA/WNWCMI/IG)
