Ajay Devgan plays prank on Katrina

Katrina is the latest victim of this serial prankster! Ajay Devgn made his Rajneeti co-star Katrina gift Nana Patekar a cake box containing old underwear, a single chappal and a fake moustache.

Recently, on the sets of Prakash Jha's Rajneeti, Ajay took Arjun Rampal and Manoj Bajpayee into confidence and pulled a joke on his leading lady.

The trio told the actress that it was Nana Patekar's birthday and they said that since he was in a bad mood, Katrina ought to wish him and present him with a gift box. Poor Katrina wasn't aware that the cake box actually contained some funny items.

A source from the unit reveals, "This prank was Ajay's brain child and he took everyone on the sets in confidence. The trio walked up to Katrina and told her it was Nana's birthday and that they were throwing a party for him. They told her that she had to dress modestly in Indian attire, as Nana was very particular about how women dressed."

Kat hurriedly dressed up in a salwar-kameez and walked up to Nana with a box given by Ajay. "When Nana opened the box he was shocked to find old underwear, a single chappal and a fake moustache as a gift. Kat was horrified."

A source close to Kat adds, "She was embarrassed and turned beet red. Everyone including Ajay, Arjun and Manoj started laughing hysterically. Nana finally told her it was a prank and that she should be more careful with Ajay from now on."
