The Ra.One star is expected to be a guest on the finale of the dance contest, Mid Day reports.
Khan is said to have agreed to feature in the last episode after being persuaded by judge Farah Khan.
The pair have collaborated on projects including Main Hoon Na and Om Shanti Om, before a high-profile fall-out in recent years.
Hrithik Roshan, a celebrity judge on the show, previously told Digital Spy: "Being part of Just Dance is simply just brilliant. I feel very awkward watching myself on TV but being part of the show has impacted my life tremendously.
"I was so touched to see the brightest dancing talents from across the globe performing on one global stage."
The Star Plus series began screening in June.
