Hrithik Roshan birthday special: Alleged affairs with Kareena, Katrina & Barbara (see pics)

With Hrithik deciding to part ways with his real life love, we bring to you his sizzling on-screen chemistry with some of Bollywood's leading divas. Sometime back he was surrounded with controversies relating to his alleged affairs with co-stars Kareena Kapoor, Barbara Mori, and his rumored link-up with Katrina Kaif. His on-screen lip-lock with Aishwarya Rai also created buzz in the media. Hrithik always tried to maintain a clean family man image but somehow things always went out of his hands. Here are some of his alleged affairs:Kareena KapoorIt was obvious that Hrithik-Kareena were the dream pair for 'Kaho Na Pyaar Hai' until Kareena decided to let down the association by walking out the film just days after the shooting started.It was rumored that Babita wanted her daughter to make debut with Abhishek Bachchan. Hrithik and Kareena were however brought together for Subhash Ghai's project 'Yaadein'. Their sizzling chemistry sparked the rumours of their affair and the couple's growing proximity towards each other. However, nothing was speculated as Hrithik and his wife Sussanne cleared the air.Years went by and Hrithik-Kareena were cast again for 'Main Prem Ki Deewani Hun', it was during this time when we heard rumors about Sussanne being upset with Hrithik's growing attention towards Kareena, which resulted in Sussanne walking out of home (rumored). Filmmakers though understood the passionate camaraderie that both the actors shared and soon they were starring together again for Karan Johar's 'Kabhi Khushi Kabhi Gum'. It was during this project that Hrithik was quite aware of the consequences that could lead up and hence he decided to maintain his distance or let's just say he became wise enough to cover up his mess. Aishwarya RaiThey were touted as the on-screen 'Brangelina' of Bollywood. Hrithik and Aishwarya became B-town's next 'It' couple overnight, there erotic chemistry in Dhoom 2 was put on show.Hrithik and Aishwarya's lip-lock for the movie became one of the best on-screen kisses of all time. Though Aishwarya's supposed in-laws - Bachchans weren't quite happy about the couple's chemistry, as Aishwarya was getting to married Abhishek in the same year. It was quite obvious that Bachchan's didn't like Hrithik-Aishwarya together; even Sussanne didn't appreciate her husband's decision to kiss on-screen. But after her marriage Aishwarya again signed up a project opposite Hrithik Roshan, 'Jodha Akbhar'. The film too showcased their hot sizzling love making scene, which again became a much talked about gossip.It is rumoured that Hrithik was given a sense of mind by his wife, after which both Hrithik and Aishwarya maintained their distances from each other, which was clearly seen in their next project 'Guzaarish'.The film tanked at box office as it failed to display their romantic sides.Barbara Mori'Kites' was Rakesh Roshan's dream project for Hrithik, he didn't want it to be a typical Bollywood flick hence he made sure that this film would be an international launch pad for his son.Hollywood actress Barbara Mori was cast opposite Hrithik, even before the film was started there were rumors about Hrithik-Barbara's growing bonding, making Sussanne even more uncomfortable than ever before. Barbara was seen accompanying Hrithik everywhere be it parties, gigs etc. The film though tanked but Hrithik's closeness towards Barbara was a nail in the coffin in Hrithik-Sussanne's marriage.It was reported that Sussanne has clearly threatened Hrithik that she would walk out of their marriage, and soon she was seen by some sources walking out of the Roshan household. With Barbara Mori going back to her place, everything seemed to have gotten back on track with Hrithik and Sussanne. Katrina KaifIt was rumored that during the filming of 'Zindagi Na Milegi Dobara' Hrithik and Katrina were getting closer, but soon realising previous threats (by Sussanne of course!) he decided to maintain distance with his co-star.The buzz is that currently he's shooting for 'Bang Bang' with Katrina Kaif and the pair maintained distance off screen. But guess it was too late for Hrithik to realise as the damage was already done. Hrithik and his wife Sussanne had parted ways.The reasons are unbeknownst to anyone but it seems Hrithik is paying the price of taking his wife's threat was too leniently.
