Apart from selecting the right kind of bikini for themselves, the trio has worked really hard to get the perfect body to carry the two-piece ensemble well.
A source said: "Bipasha, Esha and Tamannaah will be seen sporting bikinis in one sequence in the film. They have carried it effortlessly. Sajid has always had a bikini sequence in his films and 'Humshakals' is no exception."
"The sequence will surely add an oomph factor to the film," the source added.
Produced by Vashu Bhagnani and presented by Fox Star Studios, the movie will release June 20.
