It is now pretty common for dating rumours to go around when actors collaborate on a project. However, recently, such speculation has extended to instances where celebrities simply appear together. A recent example of this involves Mrunal Thakur and Dhanush. Dating rumours began earlier this month at the premiere of Ajay Devgn and Mrunal Thakur's comedy film Son of Sardaar 2, where Dhanush, an unexpected guest, made a stylish entrance. Mrunal greeted him warmly with a side hug before Dhanush continued to the red carpet for photographs.
