Rapper Rick Ross suffered a seizure on a plane serious enough to force the pilot to land so Ross could receive CPR, TMZ reports -- but colleagues of the rapper said on Twitter Friday that he was fine.

I just talked to Ross...he's 100 pct ok... tweeted rapper Wale. Soon after, someone tweeted from Ross' account in response to hip-hop journalist Elliott Wilson.

Don't scare a n---- like that. Thanks, wrote Wilson.

Ross -- or at least someone logged into his account -- tweeted: Never dat, homie.

The rapper was on a flight from Ft. Lauderdale to Memphis when he fell unconscious, TMZ said. Ross had also tweeted before the incident that he was on his way to Memphis.

Citing a witness, TMZ said Ross fell unconscious soon after takeoff and that a doctor began CPR in the air. He appeared to show signs of life as he was wheeled from the plane, and was taken to a hospital.

A call to emergency workers said he had suffered a seiure, the site said.

The Live Fast, Die Young performer, who is 35, is best known for a long feud with 50 Cent and the embarrassing revelation that he worked as a correctional officer in the 1990s.

He also performed one of the voices in singer T-Pain's Freaknik: The Musical, which aired on the Cartoon Network's Adult Swim in 2010.
