Sridevi - Madhuri Dixit

Their rivalry has been legendary to say the least. But Juhi and Sridevi never actually got personal with each other unlike today's bolly actresses who can't seem to stop themselves from plotting each others downfall. Although they never looked each other in the eye, Sridevi and Madhuri let their animosity remain at that, giving each other due respect as co-stars. And now that they don't meet each other in public, we'll never know how far can they get along?

Kareena Kapoor - Preity Zinta

Although both were never great friends, they were always cordial at events and award functions et al. But all that changed when Kareena refused the role of the bespectacled 'Naina' in 'Kal Ho Na Ho' which was then lapped up by Preity who happily portrayed the character with no inhibitions. After the movie was a hit at the BO, Kareena went around telling the media and everyone else that she was the 'original choice' for the part. Preity has not been smiling at her since then for obvious reasons. Maybe, Kareena is unaware that manners maketh a man (and woman as well)?

Mallika Sherawat - Ashmit Patel

Both made their debuts together in 'Murder'. But Ashmit was not too happy about the fact that Mallika hogged the limelight all alone. Mallika also added fuel to the fire calling Ashmit a 'cheap' actor who took a number of retakes for the lip-locks in the movie. Ashmit also had a grouse that Mallika was overly promoted during the film's release. And since then we haven't heard them saying even a causual 'Hi' to each other. Seems like one 'hot' pair, don't they?

Abhishek Bachchan- Kareena Kapoor

It is a well known fact today that Abhishek Bachchan and Karishma Kapoor were already engaged and set for marriage when things went awry between both the families and it was called off. Rumour mongers have it that Abhishek refused to work with Kareena as she is Karishma's sister. When in fact Kareena had made efforts towards friendship between the kahndaans. Now Kareena has given a tit for tat by refusing to act with Bachcchan Jr in Apoorva Lakhia's next. Looks like no chance for peace over here, Is there?

Harman Baweja- Kareena Kapoor

Kareena started it all by walking out of 'Love Story 2050' which had Harman as a leading star in it. The reason according to most is that Harman is seeing Priyanka Chopra. And of course Kareena and Priyanka have a history which isn't very pretty either. Harman took offence to Kareena's backing out and retaliated by walking out of the recent Kareena starrer to be directed by Mohit Suri. Apparently Harman did not want to be paired with Kareena. Also according to the storyline the hero falls for his step-sister and Harman could not quite agree to this concept. Are these obvious reasons for his refusal? We may never know.
