MUMBAI — Bollywood actor Ranbir Kapoor, who is having a working birthday in London, received a special birthday wish from his mother Neetu who Instagrammed a throwback photo featuring her son as a child and his sister Ridhima, NDTV reported. Ranbir, who turned 33, is currently shooting for Karan Johar's “Ae Dil Hai Mushkil,” along with Anushka Sharma, in London.
