Bollywood's rumoured love birds Sidharth Malhotra and Alia Bhatt have recently proved that they are made for each other as their thoughts are similar.

Both the actors attended separate book launch events of fitness experts and when they were asked which actress is fit in Bollywood, both said it's Katrina Kaif.

The "Brothers" actor attended the launch of celebrity fitness trainer Marika Johansson's book 'Healthy Kitchen' in Mumbai on Friday.

At the event, Sid talked about his fitness and diet while interacting with the audience. According to him, Katrina, Deepika Padukone and Jacqueline Fernandez have the fittest and hottest body.

Likewise, Alia too attended book launch of well-known fitness experts Yasmin Karachiwala and Zeena Dhalla – "Sculpt and Shape: the Pilates Way".

At the event, Alia was all praise for Katrina's figure. 

"Regarding Katrina, you see all her songs whether it is 'Chikni Chameli', 'Sheila Ki Jawaani' or 'Dhoom', she looks different in each song. She's still hot and she's still fit at the same time... she's still different. So that is something that I hope to achieve in life if I get the opportunity," Bollywood Life quoted Alia as saying.

She also talked about her fitness mantras that she had to follow according to her movie's character. "Just looking at my roles, for 'Udta Punjab', I had to lose a lot of weight because I was playing a particular character, for 'Shaandaar' I had to fit into a bikini and look desirable as a woman, not as a girl," she said.

Interestingly, when Sidharth was asked about Alia's bikini body in "Shaandaar", the actor blushed and replied in a smart way, "Shandaar looks great and Alia is a lovely girl. I am working with her in Kapoors & Sons."

This is truly 'Rab Ne Bana Di Jodi' as both of them love to stay fit and have similar choices.

After "Student of the Year", Sid and Alia will be seen romancing in "Kapoor and Sons".
