Veteran actress Rekha will be lending her vocal prowess for a promo for the controversial reality show 'Bigg Boss 15'. Rekha said: "Bigg Boss is a very 'naayab' show, that has all drama, action, fun and thrill and what's more, you get a crash course of life itself. And if one is patient and resilient, one will evolve to be one's best self! What could be better poetic justice than that."

The timeless diva will be doing a special voiceover for a tree in the promos of the show, hosted by Bollywood superstar Salman Khan on television.
