The Bachchan family hosted the biggest Diwali bash over the weekend. Now Abhishek and Aishwarya are set to jet off for a much needed vacation. Aishwarya Rai Bachchan will turn a year older on November 1 and Abhishek has planned a holiday in Rome for his lady love. Along with daughter Aaradhya, the Bachchans plan to ring in Ash’s big day in the Italian capital where the actress will be working on her professional commitments too. Once back from the long-due holidays, Abhishek will be set to begin shooting for the next schedule of ‘The Big Bull’, which is produced by Ajay Devgn. Aishwarya, on the other hand, will reportedly begin work on Mani Ratnam’s next, ‘Ponniyin Selvan’.
