Outdoor shoots are a lot of fun. And our leading Bollywood heroes never forget to play a prank or two. While shooting for Singham in Goa, Ajay Devgn told his co-star Kajal that her scene required her to thrash goons. He even handed over a belt. Kajal believed him and did what was required of her with Ajay egging her on and quipping ‘Maro Maro!’ After a point though, the unit couldn’t contain themselves any longer and burst out laughing. That’s when Kajal realised she fallen prey to a prank. She went around apologizing to all the people she had beat up. And despite his mischievous behaviour, claimed Ajay was one of her best co-stars.
