Saif, 44, said he felt like a child to share screen space with Govinda as he is a brilliant dancer and actor.
"I really respect his work and it's amazing to watch him dance. I was trying to learn something from him. I felt bit of a kid and excited especially when he was dancing. He is a genuine star and I am happy to dance next to him," Saif told PTI.
Govinda, 50, is making a comeback to full-fledged acting after a gap of three years. Next month he would be seen in two back-to-back films -- 'Kill Dill' and 'Happy Ending'.
Saif, who is also one of the producers of the film, said Govinda was apt for the film because the scenes between them looked very natural and effortless.
"It is actually really funny because if you watch the film there were atleast three-four major scenes between us. It was not that we were putting some effort to do a shot.
'Happy Ending' also stars Ileana D'Cruz, Ranvir Shorey and Kalki Koechlin in prominent roles besides Preity Zinta and Kareena Kapoor making guest appearances.
