Who's joining the Brawn party?
Always one to sniff out a celebratory soiree, The Mole gained entry into the post-Australian Grand Prix bash at Brawn HQ.
While the victorious Jenson Button was kept busy by a rigorous technical debrief with gaffer Ross Brawn, a small gathering raised a glass to the Briton's win.
Button's dad John was calming his nerves with a deserved glass of red wine after being put through the wringer for 58 laps.
Jenson's new girlfriend mingled whilst wearing his race-winner's hat emblazoned with a gold number one.
Seventies singing sensation Leo Sayer, who became an Australian citizen this year, was also on hand to toast Button.
Sayer is a lifelong Formula One fan and was a friend of the late three-time world champion Ayrton Senna, who introduced him to Brawn GP's race runner-up Rubens Barrichello.
The singer was a special guest of Brawn GP and was delighted with the team's success in Melbourne.
"I'm very close to the team," Sayer told the Mole. "I've known Ross since his early days in motor sport and I've seen Jenson in good times and bad times.
"Although Jenson led from the start, it wasn't always clear cut so it's a very emotional day, an historic occasion and a real giant-killing fairytale - and the fairy on the top of the tree is Sir Richard Branson.
"I'm hoping to come to a few more races this season as I'm just thrilled."
Sayer also revealed that he and Australian popstar Dannii Minogue - who was looking lovely at the post-race bash - were kept inside the hospitality area during the race because they had been adopted as the team's good luck charms.
After striking a timely sponsorship deal with Brawn GP, Branson was rightly partaking of a glass of champagne.
Asked what his favourite music to drive to was, the founder of Virgin Records and F1 fan said: "The Rolling Stones."
Any particular song? "(I can't get no) Satisfaction."
The Mole thinks the knight might be more than a little satisfied with his canny sponsorship deal after Brawn's one-two in Melbourne.
Aside from the scattering of loved ones, billionaires and celebrities, there was another surprise guest at the Brawn party.
BMW Sauber's Robert Kubica shrugged off his late crash to shake a few hands and offer his congratulations before slinking back up the paddock.
And that is the world of Formula 1 in a nutshell.
