Bollywood stars Akshay Kumar, Madhuri Dixit and Shilpa Shetty will be among the guest celebrities at 'The unforgettable tour', a world concert featuring the Bachchans.

"Akshay will be the guest celebrity at the inaugural function of the first leg of the tour at Toronto on July 18," Sabbas Joseph, director of Wizcraft which is producing and directing the tour, told a press conference here on Sunday.

Madhuri will be the guest celebrity at all the US cities and one show in Canada, whereas Shilpa will join the tour at the UK shows, Joseph said.

Another Bollywood actors Preity Zinta and Ritesh Deshmukh will accompany the Bachchans on the tour which was announced at last year's IIFA in Yorkshire.

With many stars having pulled out of the tour for different reasons, Amitabh Bachchan lauded Akshay's "sincerity and affection" towards him and his family.

Bachchan said he learned tips about body management from Akshay whom he kept meeting at a common gymnasium every morning. "If you eat well and exercise well, you are fit."

"I have acted with Amitji in over six films and in some movies like 'Ek Rishta' and 'Waqt', he has played the role of my father. No other actor of recent times has worked with him in so many movies like me. I plan to make the tour unforgettable for myself and my fans," Akshay said.

Bachchan said he last went on a world tour in 1990. "It is very strenuous. But, the love and affection of fans are so strong, that we decided to embark on this tour after so many years to reach out to the fans," he said.

The concert which begins on July 18 in Toronto would be followed by Los Angeles, San Fransisco, Houston, New Jersey, New York, Vancouver and London, Joseph added.
