"My camaraderie with Lara is excellent and I am extremely fond of her. I have worked with her before; so I share a certain rapport with her, " Riteish told in an interview.
"Do Knot Disturb" is his third film with the former beauty queen after "Bardaasht" and "Masti".
"As colleagues it is important to have on-screen chemistry and when you are doing comedy it is important to have the right timing and everything. Both of us understand that.
"It's great that there are times when we got a scene and we didn't need to rehearse because I know exactly what Lara is going to do and she knows exactly what I'm going to do, " added the actor who is also doing Sajid Khan's "Housefull" with the actress.
"Do Knot Disturb" also stars Govinda and Sushmita Sen and is slated to hit screens Oct 2.
The 30-year-old actor, who has emerged as a comic star after doing a series of comedies like "Masti", "Dhamaal", "Heyy Baby" and "Kyaa Kool Hai Hum" among others, revealed that his dream of working with Govinda was realised when he was offered this film.
"I always wanted to work with Govinda and David Dhawan. I'm glad that both these people came together in a single film."
So was he insecure or nervous about working with the king of comedy?
"Insecurity comes in when there is competition. In my head it is very clear that Govinda is a far superior actor. He is an institution. You cannot compete with him. Once you understand this, you are free to do as you wish and there is freedom to give your best, " he said.
But at the same time Riteish admits while shooting for the laugh riot he was on his toes.
"I was always on my toes because Govinda is such a good actor that you don't want to let him down or let the scene down because of your incompetence. I tried to do as good as possible so that I can match up to his talent and calibre. I didn't want people to say that Govinda is doing so well, but Riteish is spoiling it, " he added.
When asked about his reason to stick to mainly comic capers, Riteish, who started his career in 2003 with "Tujhe Meri Kasam", says that it is not a deliberate attempt to limit himself in one genre.
"Doing comedies is not a deliberate attempt. When certain films work, those are the kinds of offers that keep coming to you; that's the reason why I feature mostly in laugh riots, " elucidated Riteish.
"But I'm glad that now I have some films which are not comedies. So I'm looking forward to other genres. It's important for these films to do well so that more such films get offered to me."
Riteish will be seen in three non-comedies that include "Aladin", "Rann" and "Jaane Kahan Se Aayi Hai".
