Accompanied by his choreographer Mohena, Purab also grooved to the title track of his own film Rock On!!.
"It was an amazing and comforting feeling to be introduced on a Dev Saab song as a contestant in this season of 'Jhalak...'. Salman who choreographed the opening act thought it was a great way to introduce me on this song," Purab said in a statement.
"I was a bit nervous since this is a new avtaar as a dancer but once the track kicked in so did the energy," he added.
The episode will be aired on Saturday on channel Colors.
