LudacrisSince dropping Battle of the Sexes in March, Ludacris has been doing his part to raise awareness for certain public service campaigns — including an HIV/AIDS awareness project and a promotional campaign for the 2010 Census.

Now, he’s teaming with Trojan condoms to help launch their new Magnum Live Large Project. Luda will serve as their spokesman.

According to reports, the new pair-up will be Magnum’s first full-fledged advertising campaign, which will consist of radio, web and print ads. Print ads are set to run in the May and June issues of Vibe, XXL and The Source magazines.

The campaign centers around a contest that will give fans the opportunity to record a “Magun-themed” song. To enter, just visit, download music samples, record a track, and submit for consideration.

Visitors will then vote for their favorite songs, and the winner will receive $5,000, and a trip to the Birthday Bash hip-hop festival in Atlanta on June 14, where they will have the chance to hop onstage with Ludacris.
