Music star Dizzee Rascal will show that he is "bonkers" for Microsoft's latest tablet when he unveils a super-sized version of the device today.
The award-winning rapper will be dwarfed by an enormous 27x17ft model of the new Surface 2 tablet at the event in London.
Microsoft has launched the Surface 2 and Surface Pro 2 as it seeks to take on Apple, Google, Amazon and Samsung in the booming handheld computer market.
The latest incarnations of the Surface tablets were unveiled in New York last month, at which Microsoft promised improved processing power, battery life, display and camera quality over the first generation versions.
The company has also redesigned the tablet's Kickstand, which allows it to be propped up, saying it is more comfortable to use on your lap or at a desk.
Dizzee Rascal said: "I'm never in one place for long - whether it's in the studio, on tour, I'm always travelling about and now I can combine work and play on one device - works for me."
Ally Wickham, from Microsoft, said: "We're really excited to be collaborating with Dizzee Rascal on the Surface 2 launch ; he is a real inspiration for what can be achieved when you go out there and get more done.
"The Surface 2 is designed to work with you to achieve, connect and compile your personal and work worlds."
Both tablets are on sale now.
