Bollywood starlets Sidharth Malhotra and Alia Bhat are showing all the signs and symptoms of being in a relationship. Sid told Alia to refrain from talking to the media about their relationship. The `Student of the Year` co-stars are frequently spotted together at film screenings and parties. Bhatts are known for their frank nature, but Alia is quiet to keep the paparazzi away. Another Bollywood pair has also started making headlines while they were shooting for `Aashiqui 2`. Aditya Roy Kapur and Shraddha Kapoor were spotted together on several occasions, but the couple hasn`t owned up to their relationship. Rumors were rife that Aditya was allegedly getting close to his `Daawat-e-Ishq` co-star Parineeti Chopra. But that buzz is out with news that Aditya and Shraddha were together in the US for a vacation.
