New MTV reality show Twentyfourseven will start airing in the US on Wednesday, December 6.

The show will follow entrepreneur Greg, rock star Chris, club promoter Frankie, musician Cipes, film-maker Ty, actor Matt and record producer Whitman who will work together 24 hours a day to make it big in Hollywood.

MTV has also planned an extensive online presence for the show; viewers will be able to download the premiere from iTunes for free on December 6, with subsequent episodes being made available one day after broadcast in the following weeks. Exclusive after-show episodes will be made available on MTV's own website, and a special online-only Living It Twentyfourseven Challenge will see groups of friends compete against each other by facing a challenge to see who is "truly living it 24/7".
