Saif Ali Khan and Shahid Kapur [Images] seemed to have ironed their differences, after Kareena Kapoor [Images] left the latter for the former. The actors will be part of the Unforgettable Bachchan tour, which will take off in August.

But we're wondering which female stars will balance off the concert? So far, Aishwarya Rai [Images] Bachchan is the only one on board, after Lara Dutta [Images] opted out. There are rumours that Madhuri Dixit [Images] may also come on board, but that remains to be seen.

Our source informs us that the organisers are keen on getting more heroines on the tour, with no luck yet. Most of the actresses either have differences with the Bachchans, post the big wedding or are part of rival camps.

So the best option seems to be including Kareena on the tour. No only has Bebo become one of the hottest stars in the industry, but she would probably need less convincing to be with her inseparable boyfriend, Saif.

Of course, it's not clear if she would, in fact, be a part of the tour, since Shahid has signed on.
