Hands up if you fancy a boys' weekend for racing drivers in London? Stars from the world of motorsport, including nine F1 pilots, took part in the 2015 Race of Champions (ROC) inside London's Olympic Stadium.
There's hijinks aplenty at the ROC. David Coulthard, the defending 2014 champion, pretends to start a race without a car. "We're all brought together by the love of competition and the motor car," the former F1 race-winner told CNN.
There were huge cheers for 2009 F1 world champion Jenson Button from the London crowd as he took to the track in a ROC car, a bit different to the McLaren-Honda he drives for his day job.
"F1 is quite a selfish sport," says Red Bull Racing grand prix winner Daniel Ricciardo but it's a big love-in at ROC where the Australian gets the party started in the locker room.
The drivers - including Felipe Massa, Susie Wolff, David Coulthard, Jenson Button, Nico Hulkenberg and Sebastian Vettel - break out into a spot of impromptu dancing to Ricciardo's tunes.
Williams driver Felipe Massa brought his son Felipinho on the boys' weekend in London and takes time out to show him his go-karting skills at the Olympic Stadium.
It's not all frivolous fun. The drivers took the opportunity to send a message of support to ROC regular Michael Schumacher, who is still recovering from a head injury sustained skiing nearly two years ago.
Susie Wolff waved goodbye to motorsport at the Race of Champions. The 32-year-old joined the F1 driving line-up in 2012 as Williams' development driver but she was not given the opportunity to race - a fact which led to her decision to retire.
Vettel is applauded by runner- up Tom Kristensen of Denmark after winning the Race of Champions at the Olympic Stadium in London.
