Organisers of the Race of Champions event have confirmed that Jenson Button has become the fourth driver to sign up for the 2011 event.

Button, who last competed in the event in 2009 just after winning his F1 title, joins fellow F1 champions Sebastian Vettel and Michael Schumacher in agreeing to compete in the event in Dusseldorf's ESPRIT arena, while DTM racer Mattias Ekstrom will also be in action.

"I'm really looking forward to coming back to the Race Of Champions again in December," he said. "It's a great way to round off the season and it's always fun to meet up with old friends from all the different forms of motorsport. Apart from last year when I had a clash of commitments, I've turned into something of an ROC regular.

It's a lot of fun and everyone wants to put on a good show for the fans. In the ROC Nations Cup Team Germany had an annoying habit of beating us at Wembley so it's probably about time someone managed to pay them back on their home ground..."

Organiser Fredrik Johnsson welcomed the news that Button will return to the Race of Champions and Nations Cup.

"We are delighted that we will see Jenson back at the Race Of Champions in 2011," he said. "He has always been a hugely entertaining performer in this event and we've always appreciated his appearances. The last two were particularly memorable as he came to Wembley in 2008 when he didn't know if he'd still be driving in F1 in 2009. Then, 12 months later, he returned to ROC as F1 world champion. We look forward to plenty more excitement from him in December."
