Are Rishi Kapoor and Dimple Kapadia step brother and sister?

That's what I got to read here. Both did romantic movies together and even did kissing scenes in Saagar.😲

That was the strong rumor during Bobby times... Rishi was in love with Dimple and wanted to marry her but Raj Kapoor meddled cos she was his half sister or so... but I think it is a rumor cos Dimple looked almost similar to Simple Kapadia who is apparently not the love child of Raj and Nargis... and the timelines also don't match of Dimple birth and her childhood...

No 😆 but it's bw so nothing surprises me.
