The BBC Asian Network presenters revealed to Digital Spy that they are in Mumbai to unveil the ethical fashion line of hand-painted T-shirts.
"Raj and Pablo are now looking to celebrate their love of Bollywood by launching their own T-shirt range inspired by the vibrancy of retro Indian film iconography," said a statement.
"They've linked up with a British fashion designer to help create their first range of urban wear which pays homage to Hindi movies."
The T-shirt line includes the designs 'Disco', 'Vintage' and an Indian cinema take on the Union Jack.
Raj spoke to us last year about his personal favourite Hindi film: "For anybody who wants to get into Bollywood watch Om Shanti Om, it's got the golden age of Bollywood and the modern reincarnation and all the stars of course."
Raj and Pablo's 'Love Bollywood' compilation of contemporary and vintage film music, hit number one in the iTunes compilation download charts in the last quarter of 2010.
Raj and Pablo's T-shirt collection goes on sale from December 1.
