While reports have suggested that Katrina Kaif had been holed up in her house over the past few days, as she was under the weather, we heard that the actress has been raring to go back to work. Kat, who flew to Macau for IIFA, is apparently all set to fly to Prague to join the sets of her upcoming film Bang Bang. Looks like her holiday with her alleged beau Ranbir Kapoor may have to wait.
