Ranbir and Katrina, who were earlier in a speculated affair with actress Deepika Padukone and actor Salman Khan respectively, thereafter decided to move-in together. 

But, things didn't turn out the way they planned and the couple soon drifted apart.

Katrina now feels that collaborating with Ranbir again will be a tough call. For now they will be seen together in 'Jagga Jasoos' which will release on July 14th next month.

Speaking to Mid-Day, Katrina has opened up on her reasons for not working with Ranbir in the future.

"It's very difficult. People now have proof that he is a very trying and testing person. Ranbir has also gestured [to me] to not work on a film together. It will never happen again," Katrina told the tabloid.

Strangely, Katrina has also teamed up with Salman Khan for Tiger Zinda Hai, the shooting of which is underway and is scheduled to release in December this year.
