Eric McCormack may not be a cocksucker, but he sure is a screaming queen. National Enquirer - you know, the Bible of journalism - reports that the Will & Grace star recently threw such a tantrum on a plane that the FAA had to be notified:

The 44-year old erupted after the crew told him that a booster seat he brought onboard for his 4-year old son, Finnigan, was too large, violated regulations and had to be stowed with the luggage.

The actor was taking an Alaska Airlines flight from L.A. to Vancouver when crew members barred the non-regulation booster. "Eric screeched like a banshee when he didn't get his way," said the insider. "He yelled at crew members- telling them his family had used the seat on many flights in the past," said the insider. "But the price tag was still on it. And when an attendant turned over the seat, a warning label said 'not to be used on aircraft!'"

Gotta get that last word in, don't you, mary?
