Sidharth Malhotra celebrates birthday with Alia

Like last year, Bollywood actor Sidharth Malhotra celebrated his birthday with rumoured girlfriend Alia Bhatt. The 'Brothers' actor, who turned 31-year-old on Saturday January 16, rang in the birthday with Alia on the set of their upcoming film 'Kapoor and Sons'. 'The Student Of The Year' stars are dating each other for a long time now and the two were in Goa last year to celebrate Sidharth birthday. This year Sid had a working birthday as he is shooting for a dance number with Fawad Khan and Alia for Shakun Batra's 'Kapoor and Sons'. The actor cut a walermelon instead of a cake on the sets of the film with Fawad and Alia. He will also have a party tonight with some close friends and crew of the film.
