The TARDIS has landed at Westfield Stratford City bringing the Doctor and his companions to the shopping complex to launch the Series 6 Box Set released in the UK today.
Matt Smith, Karen Gillian and Arthur Darvill will all be attending the event held at the brand new mega complex adjoining the 2012 Olympic site in east London.
The three stars will be signing copies of the box-set at HMV before attending a question and answer session in the Gallery Area. Fans around the world can view the experience via the BBC Worldwide YouTube channel from 1600GMT (4PM UK, 11am ET) today. The three stars will be answering questions in a panel hosted by DJ Jo Whiley.
They'll also be updates from the event on the BBC Facebook page and Doctor Who is also taking over the BBC Worldwide Twitter channel. Fans are encouraged to tweet with the hashtag #doctorwho all day.
