Rosie O’Donnell pulled out of attending longtime friend Madonna’s “The MDNA Tour” concert movie last week after receiving a “suspicious CAT scan.”

O’Donnell was slated to sit next to Madonna during a Q&A panel, Ace Showbiz reports. O’Donnell was urged by her doctors to come back in to receive more tests which prohibited her from attending, a rep for the former talk show host informed.
An insider notes that following the tests, O’Donnell was thankfully “given a clean bill of health."

Exactly what was allegedly found on the CAT scan remains unclear.

The insider adds, "You know it has to be a serious reason to stand up Madonna."

The “suspicious CAT scan” comes one year after the comedian revealed that she suffered a heart attack. She later found that her coronary artery was 99% blocked.

O’Donnell has not officially commented on the health scare, nor has Madonna. The women became longtime pals after starring in the 1992 film, A League of their Own, Ace Showbiz notes.
