Why Katrina Kaif followed Ranbir Kapoor to the USA!

Katrina Kaif joining her beau Ranbir Kapoor and his friend Ayan Mukherji in the USA might be old news but Masala! recently discovered the reason behind Kat's US trip!

Allegedly, RK Junior was clicked with an American girl at a nightclub while he was there holidaying and relaxing with Ayan. The pictures, which went viral on a social networking site, showed the girl sitting too close to Ranbir.

Rumour has it when Katrina learnt of this she was furious as hell and allegedly booked herself on the very next flight to the US and joined the boys! Katrina had to leave the US as Kabir Khan's film had started shooting in Beirut, otherwise she would have stayed on with her beau and their common buddy.

Now, Ranbir is known to have a roving eye but his recent admission that he would give his life for Katrina if need be, should reassure her that he seems to be quite serious.
