Oh Look! A Twitter Promotion! Wow! So Cool!

Yawn.

Marketing agency I Spy is working with book retailer Waterstone's to launch their first "Twinterview," an interview to promote the launch of the TV duo's Ant & Dec's new book.

The comedic duo, Geordie, will take-over Waterstone's Twitter account (@waterstones) for one hour today at 3pm to promote their new autobiography, "Ooh! What a Lovely Pair: Our Story." Ant & Dec will answer live questions from fans and pre-Tweeted questions to the Twitter hash tag #AntnDec.

The Twitter campaign is supported by a YouTube-hosted video of Ant & Dec answering questions posed by Waterstone's customers. "What you want to know about Ant & Dec" goes live (click here to view) today.
