Mumbai: According to the latest buzz, 'Chammak Challo' crooner and international pop singer Akon was originally approached to perform at the much-hyped launch of Formula 1 after party hosted by Arjun Rampal's resto-bar.

Interestingly, it was only after the singer turned down the offer, Lady Gaga was roped in.

A source says, "Shahrukh Khan wanted Akon instead of Gaga to perform at the Formula One after parties held at Arjun Rampal's lounge.The event was being held soon after the release of RA.One, so SRK suggested Arjun, who also stars in the film, to rope in Akon”.

He adds, “The marketing genius thought it would be a perfect opportunity to do the post-release promotions of the film. Since the pop star has sung the Chammak Challo song, he could perform it at the party and help promote the film."

But alas! SRK's plan to kill two birds with one stone didn't work, as Akon didn't accept his offer. Reason? The singer wasn't apparently pleased with the money offered, which was half his market price.

It was only later that Arjun's team apparently decided to approach the pop diva Lady Gaga.Both SRK and Arjun Rampal remained unavailable for comment.
