The 26-year-old "Baaghi" star, who has been spotted with the model-actress at several occasions, will be seen romancing her in a new music video.
"I love her as a friend. We are good friends. She is fun to work with," Tiger told reporters here at the "Befikra" song launch.
"We both were comfortable with each other on and off screen. She (Disha) pushes me to do better," he added.
Disha, who will be making her Bollywood with Dhoni biopic said she shares a great comfort level with the "Heropanti" actor.
"We are good friends. We do dancing (training in dance) and sports together so we share a comfort zone. Hence we are very much comfortable with each other."
The duo said they enjoy each others company and go for outings like any two friends would go.
"We like spending time with each other. And so we go together to eat, watch films," Tiger said.
"It is normal to go out with friends for lunch, dinner and movies," Disha added The music video is shot in Paris, but the actors couldn't enjoy much as they were busy with the shoot.
"We worked very hard for this music video. We were stressed about work more (and) there was little time to have fun," Tiger said.
"Befikra" is produced by T-Series.
Meanwhile, at the song launch, Tiger sang few lines on demand of his fans. There is a step in the music video that seems similar to one of the moves of Hrithik Roshan from "Dhoom 2" title track.
"It was just a coincidence. We did this step and the director liked it as it (step) looked good. I hope I danced like him," Tiger said.
He considers Hrithik Roshan as his idol. "I am inspired by him since the beginning of his career. I idolise him. I look upto that man in every way. I am thankful to my guru. I got to share screen with Hrithik during IIFA awards recently and it's a big thing for me. All thanks to my guru," Tiger adds.
