According to a magazine Ajay and Kangna had a fling in 2010 during the shoot of Ekta Kapoor's Once Upon a Time in Mumbai. Ajay insisted that filmmakers should cast Kangna Ranaut opposite him in Tezz and Rascals. Not only this, Kangna also forced Ajay Devgn to marry her.
When Ajay's wife Kajol came to know about this, she threatened to leave the house with children - nine-year-old Nysa and two-year-old Yug.
However, everything is fine now and the couple looked happy on Karan Johar's birthday bash.
Now, we know why Kangna was missing from the promotions of Tezz and Rascals.
