The two rumoured love birds are now attending parties together.
We first spotted the two arriving hand in hand for Vidya Balan and Siddharth Roy Kapoor's party.
More recently, Ranbir and Katrina arrived together to attend Karan Johar's birthday bash on Saturday (May 25).
So why the sudden confidence? Are they perhaps thinking of taking their relationship to the next level? Can't wait to find out.
