Ranbir Kapoor and Katrina Kaif's relationship, if rumour is to be believed, has been taken to the next and more serious level with people alleging that the two stars were engaged in London in December. This coupled with their new home in Bandra, indicates that the happy twosome love each other's company. Unfortunately, with outdoor shoots coming up, the couple will be separated for a while. Katrina is shooting for Abhishek Kapoor's Fitoor in Kashmir and it has been said that Abhishek has forbidden Ranbir to visit his ladylove in the romantic and cool climes so she can completely concentrate on her role. We are sure Ranbir will miss his Kat when she's away; he need not worry, though -- she will be hard at work and not at play!
