Deepika cannot see Ranbir-Katrina together

Recently, Rishi Kapoor is shooting with Deepika Padukone for his film 'Love Aaj Kal'. While shooting, for fun he says, "I'm shooting with my Bahurani".
Deepika has been a very important part of Kapoor family, after Ranbir and Deepika started dating each other. She has been seen in all occasions in the Kapoor home. But, it seems that Neetu Singh (Ranbir's mother)dislikes Deepika. Neetu is very poossessive of his son Ranbir. She will not allow any girl to enter Kapoor house unless she is 100% convinced that she is right for her son Ranbir.
Deepika is his official girl-friend. There are rumours of Ranbir-Katrina friendhip which is growing more and more.There was a scene when Ranbir and Imran Khan were practicing for Filmfare Awards at Yashraj Studios, even though Katrina wasn't reqiired to be there, she was there from 11 in the morning chatting with Ranbir. Both of them have yet not shot for their next film 'Rajneeti'.
Ranbir and Katrina are said to be the hot-n-happeneing couple in Bollywood.
