Mumbai, March 24 (IANS) Bollywood actress Lara Dutta, who was all set to accompany Bachchans on their much talked-about world tour "Unforgettable Show", has cancelled her plans because of knee injury."I have injured my knee and have been asked by the doctors not to strain it further. Since I am also doing a big action film this year, going on the tour for three months will only aggravate my injury. So, unfortunately and regretfully I have had to withdraw from the 'Unforgettable Tour'," she said in a press release.

B ollywood icon Amitabh Bachchan will start touring the world next month along with son Abhishek and daughter-in-law Aishwarya. Bipasha Basu and Riteish Deshmukh are also expected to accompany them.
