Is Ranbir listening? Kat's going through holiday sickness

Katrina Kaif fell ill during her vacation with Ranbir Kapoor and is now recuperating in London

Ranbir Kapoor arrived in Mumbai alone from his US holiday with lady love Katrina Kaif.

The couple had flown to New York to usher in 2014. As it was extremely cold, Kat couldn't handle the weather and fell ill. Considering that she was slated to make a stopover in London to spend time with her family, she decided to extend her stay because of her health conditions.

Says a source, `Kat couldn't handle the freezing weather in the US and was down with flu. So she decided to recuperate in London. She is slated to arrive in Mumbai later this week.`

As soon as Katrina arrives she will start shooting for Bang Bang with Hrithik Roshan. There is also Jagga Jasoos with Ranbir Kapoor and Fitoor with Sushant Singh Rajput.
