The hip-hop star flew to the Big Apple ahead of a planned interview on American Tv show Live! With Kelly and Michael, but he fell ill on the plane and was hospitalised after landing in the city.
During the show, the hosts informed viewers about Nas' medical emergency and revealed he was taken straight from the airport to a local hospital to receive treatment for a severe bout of vertigo.
Nas has now opened up about the scare, telling fans he has been discharged from the medical centre and is now resting, while he also apologised for missing the interview.
In a post on his Twitter.com page, he writes, "Peace y'all (sic). I'm out of the Er (emergency room) & doin (sic) alright. I'm on bed rest for a few (days). Apologies to everyone @ Live w/ (with) Kelly & Michael. I'll make it up (to you)."
