Ranbir Kapoor is missing from the limelight, apparently working out hard on film sets. Gearing up for a much-deserved vacation in Switzerland, the actor is said to unwind at the bachelor party of his good friend Akash Ambani. Going by the elaborate wedding that the Ambani family hosted for daughter Isha, it is now time for a similar festivity for her twin brother. The party reportedly boasts of a guestlist of 500 people, including Ranbir, all of whom will be hosted in Switzerland in the last week of February. Karan Johar is also speculated to join the guys gang. On professional front, Ranbir Kapoor is busy working on Ayan Mukerji-directed ‘Brahmastra’ and another film, ‘Shamshera’, with Sanjay Dutt.
