Mona Singh will share screen space with Aamir Khan for the second time in "Laal Singh Chaddha". The actress had earlier featured alongside the superstar in the 2009 blockbuster "3 Idiots". She called him a "great guy" to work with, adding that he is "the biggest prankster" she has ever met.

"My first film with Aamir sir was `3 Idiots`. I still remember how nervous I was to shoot with him. Especially the baby delivery sequence. I was the only female in the room full of men while shooting that sequence of giving birth to the baby," Mona said.
