Most parents would be mortified if their little boy gave the middle finger to strangers. Here's why a footy star had a range of T-shirts made up when his son did it in front of thousands of fans

Jeremy McGovern’s son, Hudson, stole the show on Sunday afternoon, as his dad completed a lap of honour at the Optus Stadium.

The Eagles legend returned to the field at the 60,000-seater stadium to bid goodbye to West Coast fans following his retirement announcement.

Alongside fellow 2018 premiership hero Dom Sheed, McGovern lapped up the applause from the crowd at half-time of his side’s defeat by Adelaide.

He was joined on the field by members of his family, including his young son, Hudson, who upstaged his dad after he cheekily flipped his middle finger up at spectators inside the Optus.

And the Eagles hero and Hudson are now launching a new line of clothing, all in aid of charity.

The pair have printed a now viral photo of Hudson flipping the bird at Eagles fans during his dad’s lap of honour onto a suite of T-shirts, which are being called the ‘Give ‘em the bird tees’.

McGovern and Hudson are set to donate all the profits from the campaign to charity. They have not chosen the charity as yet, but added that it will be decided by fans.

The pair announced the brilliant move with a hilarious video on Instagram.

In the clip, which was published on Streetx’s Instagram feed, the former Eagles defender is seen standing behind his son, before introducing the campaign.

Hilariously, Hudson was seen cutting a straight face, looking directly down the camera, as he raised both his middle fingers.

‘G’day guys, we’re down here at Streetx with the “Give ‘em the bird tee”,’ McGovern said.

‘If you’re a bad boy, stick your hands in your pockets and come grab one. They’re online now.

‘If you’re a real, real bad boy, dig deep because everything is going to charity.’

Their chosen charity has not yet been revealed yet, with Streetx revealing that fans have just 72 hours to snap up their own shirt.

After Hudson performed the hilarious gesture, many Eagles fans took to social media to joke that the youngster would cop a fine from the AFL.

It comes after their star man, Harley Reid, was slapped with a $1,000 fine earlier this year, after he flipped the bird to Brisbane fans following the Eagles' defeat by the Lions at The Gabba in Round Two.

Even the West Coast’s No 1 draft pick joined in the comments on a TikTok of the viral clip, writing: ‘Respect.’

‘Suspended for two games,’ another fan joked, while another added: ‘$2,000 fine by the AFL,’ another added.

‘More like Harley Reid Jr,’ another joked, while one said: ‘Sign him up now.’

Eagles legend McGovern announced his retirement back in June due to medical reasons.

Having had time to reflect on the decision, the 33-year-old premiership legend said he was ‘at peace with the call’.

‘The game demands a lot from players and, in this instance, it is unlucky for me but at the same time, there’s a beauty to it that it can be taken away at any time,’ he explained.

‘I hope everyone cherishes it and understands what our players go through every time they run out on that footy field. It’s sad not getting the fairytale, but I’m at peace with it.

‘It’s the right decision.’
