Kiss-kiss: Max Verstappen and his partner Kelly Piquet packed on the PDA during a beach day amid their sun-soaked St Barts getaway on Sunday

Max went shirtless in light grey swimming shorts and certainly appeared to be having fun as he dove into the ocean at one point.

It comes after his father Jos hinted his son could walk away from Formula One after claiming the Dutchman is ‘a bit done with everything’ after his record-breaking season as champion.

Verstappen eased his way to a second straight title after winning 15 of the 22 races to claim a record-breaking 454 points – 146 ahead of nearest challenger Charles Leclerc in the Ferrari.

It compares to a much more challenging 2021 campaign where Lewis Hamilton went toe-to-toe with the 25-year-old all the way to the season finale in Abu Dhabi.

The Red Bull driver retained his F1 crown in style this year as Ferrari’s challenge failed to materialise after a promising start.

Jos, who drove for teams including Benetton, Tyrrell and Arrows during his own F1 career, revealed that his son is happy to have a break from the track.

He told Viaplay, as per the Mirror: ‘He’s just a bit done with everything now. Especially when you have won the championship, then the pressure is off and it becomes less exciting.

‘For Max, I think it was just important that he broke that record with those wins. I think that’s the most important thing.’

Despite his need for rest, the elder Verstappen has already turned thoughts to next season and believes it will be a much closer championship for his son in 2023.

Wow! It comes after his father Jos hinted his son could walk away from Formula One after claiming the Dutchman is ‘a bit done with everything’ after his record-breaking season as champion

He added: ‘To be honest, I do think it will all be a bit closer next year – that is also the intention of these regulations. I don’t mind. Good battles on track and a good championship until the end would be fantastic.’

After extending his record for most race wins in a season, 2022 also saw financial rewards for Verstappen according to Forbes.

So much so, he is now the sport’s biggest earner when you combine both his £33.2 million salary and the £16.6 million he earned in bonuses, leapfrogging Lewis Hamilton.
