The Bengali star was heard speaking with Garewal about her private life before filming on the episode commenced, reports Mumbai Mirror.
"Before the shoot started, both Simi and Rani Mukerji were discussing Aditya Chopra at length. In fact, Rani was looking rather happy sharing the details of her love life with the elder actress," a source revealed.
However, the Black star later denied any connection to the second-generation director.
"When Simi asked Rani about Aditya on camera, the younger actress immediately denied being in any relationship," the source added.
"This came as a surprise considering their earlier interaction off the sets. Simi was under the impression that after all these years Rani is perhaps ready to talk about her love life. And considering Rani has poured her heart out earlier, Simi was rather shocked by the denial."
Karan Johar had earlier used the programme as a platform to open up on his sexuality.
John Abraham reportedly upset former partner Bipasha Basu after discussing their relationship on the show.
