Do you expect an actress to gift an underwear to her co-star? It may sound strange but Katrina Kaif did it if the latest news is to be believed. She gave Nana Patekar some funny items including an underwear as a birthday gift.

It happened on the sets of Prakash Jha's Rajneeti. Sources said that Ajay Devgn, Arjun Rampal and Manoj Bajpayee told Katrina that it was Nana"s birthday and that they were planning to throw a big party for him. They told her to wish him and present him a gift box since he was in bad mood. They also told her to dress in Indian attire, as the actor is very particular about the way women dress.

Katrina promptly obliged their request. Dressed in a salwar kameez, she handed him the cake box. On opening it, the excited Nana was shocked to find an old underwear, a single chappal and a fake moustache in the gift box.

Sources said that Katrina blushed on seeing the odd items. Everyone on the set including Nana, Ajay, Arjun and Manoj had a good laughter. Nana told her that it was just a prank and warned her to be careful with Ajay in the days to come.

Ajay was the master mind of the prank and took the unit of the film including Arjun Rampal and Manoj Bajpayee into confidence to fool Katrina. Everything went on as planned and they had a good laughter at the end.

Well, Katrina better think twice before saying 'Yes" to Ajay next time!
