Mrs Kapoor Instagrammed a picture of the Tamasha star, captioning it for her "most beautiful soul" and circulated Ranbir's message to fans:
Ranbir was photographed arriving at a party venue along with his filmy friends - Aditya Roy Kapur, Arjun Kapoor and Aarti Shetty - on the eve of his birthday.
Ranbir Kapoor hasn't struck the right chord with the box office for quite some time now. A string of films - Besharam, Roy and Bombay Velvet -tanked, only slightly alleviated by Tamasha.
That might change next month. Ranbir has a promising role in Karan Johar's upcoming film Ae Dil Hai Mushkil, in which he co-stars with Anushka Sharma, Aishwarya Rai Bachchan and Fawad Khan.
He also has Jagga Jasoos with Katrina Kaif, directed by Anurag Basu, in the pipeline.
