Well, let's rewind the scene for all the uninitiated. Actor Ranbir Kapoor walked into the industry hand-in-hand with Deepika Padukone in 2008 and together they dreamt of a "happily ever-after". Ranbir was soon linked with virtually with every girl while Deepika got his his intitials 'RK' inked. Deepika's discomfort grew, making the much-in-love girlfriend insecure and unsettled. The final straw in break-up was his sneaking-out act with Katrina Kaif. The break-up wasn't pretty, with Deepika calling Ranbir a 'cheater' on television and blatantly displaying the tattoo (RK) that became a symbol of betrayal. However, after this much history and mystery, the two buried their past, becoming co-stars for Ayaan Mukherjee's 'Yeh Jawaani Hai Deewani'. The movie was an instant hit even before the release. The chemistry between the exes is crackling, proving that they will not let matters of the heart come in the way of career.This love story takes prime spot in Bollywood's book of love and hate relationships. Salman Khan and Aishwarya Rai (now Bachchan) began dating in 1999, while shooting for 'Hum Dil De Chuke Sanam'. By March 2002, they had an ugly breakup. Aishwarya accused Salman of abusing her. Reports claimed that Salman, unable to accept the break-up, had started harassing and hounding and even threatening Aishwarya. He apparently even slapped a journalist once for asking him questions about Aishwarya.

Their relationship ended on a turbulent note and even after 10 years they don't see eye-to-eye. Each has moved on; one married has a little kid and the other reached superstardom but they still take calculative measures to avoid bumping into each other. Not that their separation affected their individual careers (not Salman's for sure) but their bitterness is too unpleasantness to swallow. While Salman can still be good friends with another ex-Katrina Kaif and give one of biggest hits of 2012, we wonder what will take to see Salman-Ash share screen-space (forever?). Hence a Salman-Aishwarya specimen only sees audience lose out on experiencing the chemistry between one of the most beautiful couples on-screen.It was the one of longest relationships that Bollywood has seen, and a break-up that stumped many within the industry. But Shahid Kapoor and Kareena Kapoor have always been civilised about their separation. She fell for Saif Ali Khan during the shoot of 'Omkara', leaving Shahid completely heartbroken. Took him few months to recover and go on a dating spree.  However, post the break-up released their first and one of the biggest hits of their careers 'Jab We Met'. Kareena went on record to say, "Shahid and I can never have any bad blood." When Kareena tied the knot with Saif, a very callous reporter asked Shahid about his thoughts. Shahid gave a dignified reply wishing Saif and Kareena well. And though there is a very lean chance that they would star opposite each other, we would like to see that 'Jab We Met' spark once again! Since we do not see any enemity even after heart-break we keep our hopes alive.
