Produced by Lime Pictures, the show's next series will be extended to eight episodes.
"Audiences have been hooked on the show," said MTV in a statement. "Since its launch this June, it has become the highest-ever rated series on MTV.
"The Newcastle-based show that brought 'tanning', 'tashing on' and 'getting mortal' to the masses will be returning in early 2012, filmed once again in and around the North-East town famed for its lively nightlife and larger-than-life characters."
MTV is currently airing summer Magaluf Madness specials, which the cast filmed while on holiday in the Spanish island.
