What actors and actresses appeared in Untitled Snoop Dogg Singing Competition Project - 2012?

There seems to be some confusion. There is no record of a "Untitled Snoop Dogg Singing Competition Project" from 2012. Snoop Dogg has been involved in various projects, including reality TV shows like "Dogg After Dark" and "Martha & Snoop's Potluck Dinner Party," but there's no known singing competition project with that title or release date.

If you have any more details about the project, please provide them, and I'll try to assist you further.
