Button signs up for Race of Champions
Former Formula One champion Jenson Button has signed up for December's Race Of Champions in Dusseldorf.
McLaren driver Button missed last year's event but will return to make his fourth appearance on December 3-4.
"I'm really looking forward to coming back to the Race Of Champions again in December," said the Briton.
"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."
The ROC pits some of the best drivers in the world from a variety of disciplines - including the World Rally Championship, World and British Touring Car Championships, Le Mans Series and NASCAR - against each other on a specially constructed track inside a stadium.
There is an individual competition on the Sunday after drivers from the same countries have paired up for the Nations Cup on the Saturday.
"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," said Button of his rivalry with Schumacher of Mercedes and Red Bull's reigning F1 champ Vettel.
Race organiser Fredrik Johnsson said: “We are delighted that we will see Jenson back at the Race Of Champions in 2011.
"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.”
Button has won the Canadian and Hungarian Grands Prix this season to sit fifth in the drivers' standings.
Vettel leads the championship with 234 points to the 149 of nearest rival and team-mate Mark Webber, while seven-times champion Schumacher is down in 10th.
