Jenson Button has become the third Formula 1 World Champion to sign up for this year's Race of Champions, joining Sebastian Vettel and Michael Schumacher.
2009 F1 title winner Button last contested the RoC in his World Championship season, when he reached the semi-finals and took Great Britain to the Nations Cup final in partnership with Andy Priaulx.
"I'm really looking forward to coming back to the Race of Champions again in December," said Button. "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..."
RoC chief Fredrik Johnsson welcomed Button back to the event, which takes place in Dusseldorf's ESPRIT Arena on Dec. 3-4.
"He has always been a hugely entertaining performer in this event and we've always appreciated his appearances," said Johnsson. "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."
