Bollywood's producer-actor Kamaal Rashid Khan (KRK), who is known for his controversial tweets, has landed in trouble once again.

Recently, Khan tweeted racist remarks against south superstar Rajinikanth. "South superstar was the most handsome super star or the worst looking super star of all time?" Kamaal wrote. Apparently, the tweet did not go down well with Rajinikanth's fans.

The superstar's fans have condemned the racist tweet against their "Thalaivar" (leader), who is hailed as one of India's finest actors.

This is not the first time that Khan has posted controversial tweets. In fact, the actor has also targeted Rajinikanth's son-in-law Dhanush for his looks. In August, Kamaal made defamatory remarks against Dhanush in his review of the "Raanjhanaa" film uploaded on video-sharing site YouTube.

Kamaal said in the video, "Sir, I don't know whether you (Anand L Rai, the film's director) are from UP or not, but I am. In the whole of UP, you will find cobblers and sweepers who look like Dhanush but you will not find a single Brahmin of such dirty looks as him in entire UP."

A case was registered against Khan for making casteist remarks. Since then, the controversial remarks have been removed from the video.

In the past, Khan had targeted numerous celebrities including Sunny Leone, Preity Zinta and Poonam Pandey. The twitter war between Sunny and Kamaal reached to such an extent that Sunny threatened to take legal action against the actor.

Khan was born in Deoband, Uttar Pradesh in 1975. He left his home and arrived in Mumbai to become an actor. Failing to make it big in the film industry, Khan started a garment and construction business. He made good money through construction business and returned to cinema. He made his debut as producer with 2005-flick "Sitam." Since then, he has produced, directed and acted in many low-budget Hindi and Bhojpuri films, reported The Times of India.

Khan made headlines for his controversial flick "Desh Drohi" and also appeared in Big Boss season 3.
