Senegalese-American R&B singer Aliaune Badara Akon Thiam, better known as Akon, will be arriving in Mumbai this week to sing on the soundtrack for the upcoming Anubhav Sinha film, 'Ra.1.' While there have been rumors floating around that the vocalist will act in the movie, those were denied by Sinha, who stated, "Akon is only singing for our film. He is not acting in 'Ra.1'."

The film is being composed by the team of Vishal Dadlani and Skekhar Ravjiani, who have previously served as musical directors for 'Jhankaar Beats,' 'Om Shanti Om,' 'Tashan' and 'Bachna Ae Haseeno.' Akon is also expected to return to India in April for live engagements alongside singer and composer Aadesh Shrivastav.

The film 'Ra.1' features Shah Rukh Khan, who will lip-sync Akon's lyrics in the movie. Khan roped in Hollywood writer David Benullo to write the screenplay for this futuristic sci-fi thriller, in which he plays a superhero.
