Since its inception (season 1), Geeta Kapur, Terence Lewis and Remo D'Souza were synonymous with the show, but they have been replaced by the new faces.
Mithun Chakraborty, seen as grandmaster in the show, says the new judges will add up to the growth and progress of the show.
"Geeta (Kapur), Terence (Lewis) and Remo (D'Souza) are a part of 'DID' and will always be," Mithun said here Wednesday at the launch of the show.
"But I believe that change is the sign of growth. Wherever there is a change, be sure there has to be a change, and because of this only this time we have three new faces who think alike me, believe in me," he added.
Feroz, Mudassar and Shruti may be donning the judges hat for the first time, but the trio has proved themselveds with their work.
Feroz is credited for choreographing for films like "Anjaana Anjaani", "Ra. One" and "Agneepath", while Mudassar has choreographed for "Ready", "Bol Bachchan" and "Bodyguard".
Shruti, younger sister of choreographer Vaibhavi Merchant, assisted her sister in "Dhoom" series, "Aaja Nachle", "Rab Ne Bana Di Jodi", "Kal Ho Naa Ho" and "Devdas".
The fourth season of "DID" will witness international dance forms as well, along with African dance forms.
"This time we are set to go international (in dance forms), this time there are many new dance forms, in fact we have also included African dance form. So there are a lot of things that we want to present to you," Mudassar said here.
"We have made a list of many of the dance forms. But the 100 dancers we have selected are talented enough to do those dance forms. So it is not only a big challenge for us, but also a huge responsibility," he added.
"Dance India Dance" season 4 is set to go on-air Oct 26 on Zee TV.
