The Bachchans' upcoming Unforgettable world tour has something to look forward to - leggy lass Shilpa Shetty is all set to team up with Aishwarya Rai for two performances.

Shilpa is preparing to dance the night away with Aishwarya, Amitabh and Abhishek Bachchan in London Aug 23-24 at the prestigious 02 Arena, earlier known as the Millennium Dome.

But this is not Shilpa's first show with Amitabh.

"I've been on a world tour with Amitji earlier, but not with the rest of the family. And Preity Zinta, who will also be coming along, is a terrific hassle-free girl. As for Aishwarya, we're both from Mangalore. I'm looking forward to going on stage with her," Shilpa said.

Shilpa's popularity soared in Britain after her stint in reality show Big Brother, which she went on to win.

And what made Shilpa join the Unforgettable tour at the eleventh hour?

"It's not a last-minute thing at all," said Shilpa. "I had been in negotiation to join the tour for a while. It finally worked out now. I'm looking forward to going on stage with the Bachchans."

While Shilpa will join the Bachchans in London, Madhuri Dixit is expected to perform in the US and Canada and Akshay Kumar will be seen at the inaugural show in Toronto July 18.
