Katrina takes off to New York to tend to her health as Ranbir Kapoor vacations in the US

Post the debacle of his latest film, Besharam, Ranbir Kapoor took off to New York for a vacation. Guess who followed in his footsteps soon after? RK's girlfriend, who apparently had been suffering from a viral flu, flew off to the US to join him. Sources close to the actress say Kat left the Indian shores to New York to help her recuperate.

Says the source, `Katrina was expected to join Ranbir on his holiday but she was delayed after falling ill. She was down with a viral flu and had been wrapping up her work, which included a song shoot for Dhoom 3. As soon as she was done, she decided to take a break and rest in US.`

Insiders say Kat allegedly was feeling so under the weather that she had to seek medical assistance on the sets. `Kat has a tight schedule as she is getting ready to start work on Kabir Khan's next film. She also had to wrap up her endorsement shoots.`

Buzz is that over the weekend, onlookers spotted the couple catching up on a film in a local theatre in Manhattan. The actress' spokesperson remained unavailable for comment. Hope the American air helps Kat feel better.
