In the modern world, relationships are as fickle as they come. Actors are together or not in their personal lives, work has to go on. HitList analyses a few of those equations.

Salman Khan and Katrina Kaif
The two split in 2009 after apparently Katrina started dating Ranbir during the making of Ajab Prem Ki Gajab Kahani. But the two remain cordial with each other. Salman Khan performed with her in an item numbers for Tees Maar Khan before working with her again in Ek Tha Tiger. She is known to visit the actor's place regularly. Though chances of the two coming together for a film seem slim, it may be noted that Salman and Katrina's film Yuvraj had tanked at the box office.

John Abraham and Bipasha Basu

Their eight-year relationship ended on a bitter note. Though John hasn't spoken about her for a while now, Bipasha has often hinted at the actor having caused the split. When the two were together, the couple was also approached by product companies for endorsements. Since their split, they haven't worked together.. There were recent reports that Bipasha was considered for a cameo in Shootout at Wadala but was dropped as John was against her being cast in the film. She was eventually replaced by Sunny Leone in the film.

Ranbir Kapoor and Deepika Padukone

The two worked together in Yeh Jawani Hai Deewani (YJHD) and they will pair up again in Imtiaz Ali's next film that goes on the floors in June this year. The actors were seeing each other during the shoot for Bachna Ae Haseeno and initially the film did average business at the box office. Then came their split and the release of YJHD, which was a resounding success. The two are now open to working with each other and are good friends too.

Priyanka Chopra and Harman Baweja

This couple may no longer be together but the two are on talking terms. When the first look of Harman's film Dishikyaoon was recently launched, Priyanka Chopra sent out a tweet congratulating the actor, and wishing him good luck. It may be recalled that Priyanka and Harman dated each other for more than a year and worked together in two films: Love Story 2050 and What's Your Rashee? Clearly, the two have moved on.

Anushka Sharma and Ranveer Singh

They started dating each other during the making of the film, Band Baaja Baarat. The two were cast opposite each other in Maneesh Sharma's second film, Ladies Vs Ricky Bahl. The two apparently split after the actor expressed his displeasure over Anushka's friendship with another actor. But the two will star together in Zoya Akhtar's next film. Ranveer Singh has reportedly said that he is looking forward to working again with Anushka. He even has given her the credit for making him a better actor.

Hrithik Roshan and Kareena Kapoor
It took them a decade to finally come together again in Karan Malhotra's film Shuddhi. Kareena has been eager to start work on the film but the shoot has been delayed due to Hrithik's ill-health and his separation from wife Sussanne. The two last worked together in Sooraj Barjatya's film, Main Prem Ki Diwani Hoon. This 2003 film failed to make a mark at the BO. After that due to personal issues, they didn't work with each other.

Shahid Kapoor and Priyanka Chopra

Though neither of them have confirmed or denied their relationship, rumour mills have been buzzing with news about their romance. Recently when Karan Johar quizzed PC on his show about Shahid Kapoor, she replied saying, `Gandi Baat.` It is said that they broke up during the making of Teri Meri Kahani and theirs was a cordial split. We wonder if the two will come together in Vishal Bhardwaj's Kaminey2.

Shahid Kapoor and Kareena Kapoor

It is being said that their split was an acrimonious one and things don't seem to have improved between the two. Grapevine has it that the actress and the actor had a showdown during rehearsals for an award function. The two, who dated for more than two years, went separate ways during the making of Jab We Met. Interestingly, their films - 36 China Town, Chup Chup Ke and Fida -- failed to work magic at the box office.

Blast from the past
Madhubala and Dilip Kumar: Dilip Kumar and Madhubala worked together in four films. The two stars broke up just before the making of Mughal E Azam and despite their differences, they went on to act in films such as Tarana, Sangdil and Amar.

Rekha and Vinod Mehra: Rekha and Vinod Mehra starting seeing each other during the making of the film Elaan in 1971. The two were said to be married but the actress denied this. The two came together after their split in Manik Chatterji's film, Ghar that was very well-received by the audiences.
