Valentine's Day is about love and romance, and Bollywood is the place that teaches how to be romantic like Shah Rukh Khan in most of his movies or how to express your love like Alia Bhatt in "Humpty Sharma Ki Dulhania."

Like Raj-Simran from "Dilwale Dulhania Le Jayenge," Bollywood has given birth to several on-screen romantic couples. Their romance touched millions of hearts and proved to be a big factor in ensuring box office hits for many movies.

Recently, the comeback of Shah Rukh and Kajol in "Dilwale" and Ranbir Kapoor and Deepika Padukone in "Tamasha" was a treat to their fans. Also, Ranveer Singh and Deepika has always captured hearts on- and off-screen.

Alia too looks adorable sharing screen space with Varun Dhawan as well as with her rumoured boyfriend Sidharth Malhotra.

Shah Rukh-Kajol

Bollywood's most romantic couple, Shah Rukh and Kajol, appeared on big screen in 2015 after five-years' gap. The duo starred in Rohit Shetty's "Dilwale" last year, which turned out to be a flop at box office. Kajol and SRK are one of the evergreen jodis in Bollywood.

Ranveer-Deepika

Another most-loved pair, Ranveer Singh and Deepika Padukone, captured hearts with their chemistry in "Bajirao Mastani." The duo, who are rumoured to be dating in real life, have always managed to mesmerise audience whenever appeared on-screen.

Varun-Alia

Varun and Alia had given a glimpse of their romance earlier in Karan Johar's "Student of the Year." In 2014, the two romanced each other in "Humpty Sharma Ki Dulhania." They were so comfortable with each other on-screen that back then B-town was buzzing with romours about their dating each other. However, after the release of the film, those gossips evaporated. Reportedly, Varun and Alia are casted in Johar's "Shuddhi."

Ranbir-Deepika

Post the break-up, Ranbir and Deepika stole hearts with their chemistry in "Yeh Jawaani Hai Deewani" in 2013. After parting ways, the duo were maintaining a cordial relationship and then made a comeback last year with Imtiaz Ali's "Tamasha."

Alia-Sidharth

Bollywood's rumoured couple, Alia and Sidharth, have appeared in Johar's "Student of the Year" and became one of the favourite jodis in the industry. Since then, fans were eagerly waiting to see the duo on big screen and now the pair will feature in Dharma Productions' "Kapoor and Sons."
