Lionel Messi's son, Mateo, took his gum out and CHUCKED it into the crowd, prompting a furious reaction from his mum.
The Argentina captain scored his side's opening goal in their 2-1 victory last Saturday to book their spot in the next round of the tournament.
The crowd erupted after the 37-year-old hit the back of the net, with his son going wild in the stands to the anger of his mum.
A video shows Mateo being a cheeky little bugger as he took his gum out of his mouth and launched it into the crowd.
Antonela Roccuzzo stood out of her seat and gave him a telling off as she tried to restrain him.
The Paris Saint-Germain forward will be hoping his son cuts a more composed figure for Argentina's quarter-final clash against the Netherlands.
Ahead of the big showdown, Louis van Gaal believes he's spotted a flaw in Messi and plans to exploit it in their showdown.
"Messi is the most dangerous creative player, he is able to create a lot and to score goals himself," the Dutch boss said.
"But when they lose the ball and the opponent has possession he doesn’t participate much, and this gives us chances [to exploit].
"I was very critical at half-time in my analysis that I share with my players
"Although we were in the lead 2-0, I think they were fantastic goals with beauty and team spirit."
The 71-year-old added: "However, in the first half we were dispossessed so much and it was not necessary.
"That’s simply not acceptable at a World Cup. If you play top-notch countries, you simply can’t make those mistakes.
"In the second half they did a much better job I think even though we scored fewer goals.
"Nonetheless, we were all very, very pleased and it gives us incredible confidence.
"I think we have big chances here. We still have three matches to go. I’ve been talking about this for a year that we can become world champions."
