This news is simply flying around in the tinsel town and making everyone sit up with surprise.... B-Town's much talked and hottest couple - Ranbir Kapoor and Katrina Kaif - is said to have eventually sealed their relationship with an engagement..! Yeah you read it right!

Hot buzz is that this 'Ajab Ghazab Ki Prem Kahani' ki jodi exchanged rings on 30th December 2014 in London - Kat's home city. Of course held in a very hush-hush way, the private ceremony was said to have attended only by very close friends and family of Ranbir and Katrina; that including the 'Rockstar' actor's parents Rishi Kapoor and Neetu Singh.

If sources are to be believed, Katrina was celebrating the Christmas holidays with her family in London, when Ranbir joined her later. He was supposed to go New York with his buddy, filmmaker Ayaan Mukherji, when he changed course and sought to be with his lady love, to celebrate the New Year instead.

Well, the news seems to be quite unbelievable... But if its true, then our Hearty Congratulations!!!
