My issues with Karan Johar strictly personal: Ajay Devgn

In September, Ajay demanded an investigation against Karan, who allegedly paid actor Kamaal R. Khan Rs 25 lakh to tweet positively about "Ae Dil Hai Mushkil" and to write negative reviews for "Shivaay". "We have our issues and that's strictly personal, and nothing professional. Those are personal issues and I don't want to talk about it," Ajay told media here. The industry buzz is that Karan's "Ae Dil Hai Mushkil" could face trouble in getting a release as it stars Pakistani actor Fawad Khan. The Maharashtra Navnirman Sena has already threatened it won't let any film with Pakistani artistes release.
