Since the bitter break-up in 2009, the duo have come a long way.
So much so that they are even romancing each other on screen.
Rumours are rife that Katrina and Ranbir are all set to marry in the coming months, and that they even exchanged rings in London on Dec 30.
The couple moved in together at a plush Bandra flat last year and since then there has been constant speculation on their wedding date.
While Ranbir and Katrina have kept mum over the wedding date, tabloids are speculating the D-Day to be in 2016.
Meanwhile, Deepika is dating Ranveer Singh, who dotes on her and never fails to show it off in public .
Seems like Deepika Padukone is in no mood to let go of any opportunity to take digs at her ex boyfriend and his current flame (Ranbir Kapoor and Katrina Kaif).
Yesterday, we heard Deepika jokingly advise Katrina Kaif not to marry Ranbir Kapoor and today a new video has come out of Deepika taking pot shot at the couple yet again.
At the recently held Star Guild Awards 2015, when Deepika Padukone was asked what would be her New Year resolution if she was Katrina Kaif.
"If I was Katrina Kaif, I would marry Ranbir Kapoor," pat came the reply from the actress.
Interestingly, at another recent award function Deepika joked, "Do not marry Ranbir Kapoor," when she was asked what advice would she give Katrina Kaif, for a behind the scene video.
Well, we wonder what's with Deepika's Ranbir-Katrina fixation?
