Rishi, an avid user of social media, took to Twitter, where he shared a photograph of legendary musician Frank Sinatra. On the image, it was written : "Frank Sinatra on Robert Redford: 'Well he found true love - What a pity he can't marry himself.'"
The 63-year-old actor captioned the image: "I have worked with some 'I, me, myself' actors, no naming. Totally obsessed with themselves. Sinatra Babu sums it up well."
The actor has been a part of the industry for over four decades and has given hits like 'Mera Naam Joker', 'Bobby', 'Khel Khel Mein', 'Hum Kisise Kum Naheen', 'Karz' and 'Prem Rog'.
The 'Eena Meena Deeka' star has shared screen space with a string of A-listers including Amitabh Bachchan, Rakesh Roshan, Sridevi, Ajay Devgn, Kajol, Hrithik Roshan and Alia Bhatt.
