Serious news for funnyman Tracy Morgan.
The 30 Rock star, 43, is currently being hospitalized at Park City Medical Center in Park City, Utah after collapsing at a Sundance Film Festival event Sunday night.
UPDATE: Morgan's rep tells Us Weekly: "From a combination of exhaustion and altitude Tracy is seeking medical attention. He is with his fiancé [Megan Wallover] and is grateful to the Park City Medical Center for their care. Any reports of Tracy consuming alcohol are 100 percent false."
Promoting his film Predisposed, Morgan was an honoree at the Creative Coalition Spotlight Awards and gave a speech -- and some subsequent reports claimed he was intoxicated. After being escorted outside following his speech, Morgan collapsed, and an ambulance rushed onto the scene, according to ABC News.
A diabetic, Morgan received a kidney transplant two years ago. He and model Megan Wallover confirmed their engagement last September.
By Monday afternoon, Morgan was cracking jokes about the incident. "Thank U 2 the hospital staff. Back at work 2morrow shooting 30 Rock. Holla at me!," he tweeted. "Superman ran into a little kryptonite. The high altitude in Utah shook up this kid from Brooklyn."
