Seems like the magic of India's Dancing Superstar is spreading all over. Even the judges Riteish Deshmukh and Geeta Kapur couldn't resist themselves from a very unique competition. Riteish, who is very fond of contestants Padmini and Debashish, gave a challenge to both of them to find out who is stronger than the other and the challenge was an arm wrestling competition. After watching the contestants, even Riteish and Geeta got very excited and decide to try their hand at arm wrestling. The duo went on stage and had a fun-filled arm wrestling competition which generated a contagious laughter on the set. "We were very surprised when Riteish sir and Geeta ma'am came on stage for an arm wrestling competition; they are very sweet and help us face competition in a positive manner. IDS has changed our lives," says Debashish. Moving on, Amardeep Singh Natt, the zinda Robot from Amchi Mumbai on the show yet again impressed the judges with his amazing robotics style. The talented dancer was so perfect in his dance that even Vidya Balan, who came in to promote her movie Ghanchakkar, was speechless after watching his performance. Seeing his act, the beautiful actress gave a challenge to Amardeep to perform with a feather scarf which she had brought along with her. The multi-talented dancer accepted the challenge and gave a mind blowing performance and also shook a leg with his favorite actor Emraan Hashmi. “I am very happy to be a part of India’s Dancing Superstar and thankful to them that I got the chance to perform in front of my favorite actor,” says Amardeep. The sequences will air this weekend.
