The actress will be seen taking on a supporting role in the upcoming ensemble drama Race 2.
She told Hindustan Times: "Even Asin was the bigger star in Housefull 2, but we got along well. Similarly, I got to learn a lot from Deepika [Padukone] on the sets, she is extremely focussed.
"I think if you are the smaller star, you already know the bigger star will get the bigger role. It's important that you know that and don't come to the sets thinking that you are this huge star. You will ruin it for yourself.
"You want your movie to do well, and they have a larger fan base who will watch your film."
In February, it was reported that Fernandez and Padukone were "bonding" before production began.
The Sri Lankan star had previously described Bollywood actors as "ruthless" rivals.
