Kajol and Karan Johar's friendship has been going strong since the beginning of their career, but now it seems their relationship is in trouble. The recent buzz is that Ajay Devgn created a rift between Kajol and KJo.

Ajay's "Shivaay" is clashing with KJo's "Ae Dil Hai Mushkil" at box office as both the films are scheduled to be released on Oct. 28. Thus, the "Dilwale" actress has to choose sides between her good friend and husband, and obviously, Kajol will go for Ajay. Earlier, Kajol has done the same when Ajay's "Son of Sardaar" clashed with Shah Rukh Khan's "Jab Tak Hai Jaan."

"Ajay's 'Shivaay' is the real reason for the strain in Kajol's friendship with Karan. Kajol is staying away from Karan because his film 'Ae Dil Hai Mushkil' will be clashing with her husband's. Obviously she has chosen her side like the last time she did with Shah Rukh," Bollywood Life quoted a source as saying.

The report suggests that Kajol has stopped talking to Karan, and, in fact, she has not wished the filmmaker or attended his birthday bash in London. However, Kajol made a comeback on Twitter handle to share her husband's film "Shivaay" poster.

Karan and Kajol had last worked together in the former's directorial "My Name Is Khan." Meanwhile, Karan is busy shooting his upcoming film "Ae Dil Hai Mushkil" and it is after three years that the filmmaker is helming a movie. The romantic drama will feature Aishwarya Rai Bachchan, Ranbir Kapoor, Anushka Sharma and Fawad Khan.

On the other hand, Ajay and the makers of "Shivaay" are making fans curious with the posters they have released on social media. Also featuring Sayesha Saigal, "Shivaay" has been shot mostly in Bulgaria and Ajay will be seen acting, directing and producing it.
