Despite being in the midst of promotional activities for her upcoming next, Bollywood’s Numero Uno Kareena Kapoor has jetted off to London, where she will join Saif Ali Khan as the duo will together attend an auction hosted by the Pataudi family, to raise funds for the new Tiger Eye Hospital.

The actress will auction her signature "Chammak Challo" saree from the film ‘Ra.One’ - proceeds of which will go towards the hospital, whose endeavour has been to help visually challenged people.

The auction, to be held in London, will see author Jeffrey Archer wielding the hammer.

Apart from Kareena’s saree, the auction will also see a tee signed by footballer Lionel Messi and a bat autographed by Rahul Dravid to name a few.
