MUMBAI: American rapper Armando Christian Pérez, popularly known as Pitbull has sung and penned the theme song titled 'Back In Time' for the highly anticipated action movie 'Men in Black 3'. The announcement was made by Lia Vollack, president of Worldwide Music for Sony Pictures.

Along with Pitbull, the lyrics of 'Back In Time' are also written by Marc Kinchen, Adrian Trejo and Urales Vargas. It features a sample of the 1950s hit 'Love is Strange', written by Sylvia Robinson, Ellas McDaniel and Mickey Baker.

Pitbull said, “It's an incredible honour to be a part of such an amazing franchise as 'Men in Black' and I have so much respect for Will Smith, especially with our similar musical backgrounds. Wanting to keep the music fun yet modern, we used the slogan of the movie and flipped it back into the song that 'in order to understand the future, you have to go back in time'.”

Film director Barry Sonnenfeld said, “My 19-year-old daughter turned me on to Pitbull. I'm thrilled that he wrote such a great song for our movie that totally gets it.”

The song will be available as a digital single and released on radio on 26 March.  The movie will be released in 3D in theaters nationwide on 25 May, 2012.
