He is a proud father to four children he shares with wife Victoria Beckham.
And enjoying some quality time with his teenage son Romeo Beckham, 16, on Saturday, David Beckham was seen planting a kiss on his child's head as they attended the closing ceremony of the Invictus Games in Sydney.
The former footballer, 43, has been enjoying a trip Down Under with his family, but made sure to turn out for the ceremony, hosted by Prince Harry and his pregnant wife Meghan Markle.
David cut a dapper figure for the occasion in a two-piece navy suit to ensure he was honouring the cause in a respectful manner.
He teamed the suit with a white shirt underneath and matching tie and appeared in high spirits while attending the multi-sporting event that sees wounded, injured and sick armed services personnel come together to compete.
He was joined by model Romeo who looked just as smart as his famous father in a light blue Ralph Lauren shirt.
David and Romeo were pictured enjoying the spectacle of this year's Sydney Invictus Games, with David sweetly planting a kiss on his mini-me at one moment.
The duo were also seen enthusiastically clapping in the crowd, both beaming from ear-to-ear as they watched the event unfold in front of them. Both Prince Harry and wife Meghan had made speeches at the ceremony.
In a short and 'personal' speech to the 12,000-strong crowd in the Qudos Bank Arena, Meghan thanked organisers and athletes for welcoming her into the 'Invictus Family.'
She praised the 'unshakable bond' between servicemen and women and the 'camaraderie and close-knit sense of community' she has experienced at the Games.
The Duchess, 37, was followed by a performance from The Kingdom Choir, the gospel choir that sang at Harry and Meghan's wedding.
Prince Harry took the stage to rapturous applause. He opened his relaxed speech by saying 'Hi guys' and told veterans he was 'humbled and inspired by your determination, your service, and your sense of humour.'
In a moving tribute to competitors, he said the Games was made up of 'ordinary people doing extraordinary things' who have 'exceeded every expectation.' He added: 'No challenge is too difficult to overcome.'
David's appearance at the closing ceremony comes after he told his fans on social media that he and his boys had been left 'inspired' by the tenacity of the Invictus Games athletes.
Beneath a photo that showed him with Romeo and Cruz, David wrote: 'Special day at the @invictusgames2018... So inspiring in so many ways.. All I can say is WOW!'

The Duke and Duchess returned to Sydney just in time to watch the final day of the Invictus Games, where Meghan has donned two chic outfits.
The first comprised a Scanlan Theodore belted jacket, teamed with jeans and pumps, while the second took a more formal approach with a tailored dress by Antonio Berardi.
Meghan is renowned for her elegant, sophisticated style, and this number didn't fall far from her signature aesthetic. The tuxedo-inspired design incorporated a fit-and-flare silhouette with statement lapels and halter neck. Meanwhile, the khaki hue is bang on trend and universally flattering on all skin tones.

The former Manchester United ace is an ambassador for the 2018 Invictus Games - annual sports competition for injured war veterans.
While attending the Invictus Games, David spoke told the ABC that his children are relishing their time together in Sydney. He said: 'To bring the family over, to make them experience something like this is pretty incredible.
'It's the icing on the cake for them to be here with their dad and their mum for a week. And then come to the games.'
It came after David hit headlines for controversially suggesting his marriage to former Spice Girl Victoria Beckham takes 'hard work' in an interview with Australian TV show The Sunday Project.
He said: 'I think marriage is always hard work, your children, they want your time and they deserve your time. And difficult situations like being away from each other. You make it work.'
Discussing the public interest in his marriage, David admitted that he's learned to focus on the positive. He shared: 'I've grown to ignore the negative stuff. I think if you know each other, you know you have great friends, a great family behind you. The thing we have to do is protect our children.'
It came weeks after David's absence from a Vogue magazine cover shoot featuring his family sparked rumours of trouble in paradise.
Back in June, unsubstantiated rumours circulated on social media that David and Victoria were heading for a divorce, but the power couple were quick to dismiss the reports, with a spokesperson branding the speculation a 'crock of s**t'.
After tying the knot in Ireland in 1999, David and Victoria have spent years defending the state of their relationship and denying claims they are on the brink of divorce.
MailOnline contacted representatives for David and Victoria at the time.
The couple, who began dating in early 1997, share four children - Brooklyn, 19, Romeo, 16, Cruz, 13, and seven year-old Harper.
