David Beckham caught his youngest son trying to sneakily drink champagne.

The 36-year-old soccer star spotted Cruz, six, attempting to enjoy a tipple during the post-match celebrations following his last game of the season for Los Angeles Galaxy on Sunday night (20.11.11) - which saw the team win the MLS Cup - by standing with his mouth open next to players spraying the alcoholic drink at each other.

Speaking on the 'The Jimmy Kimmel Show' last night (23.11.11), David - who also has sons Brooklyn, 12, Romeo, nine, and four-month-old daughter Harper Seven with wife Victoria - explained: "The funny thing was in the lead-up to the game my son was like, 'Daddy what do you do after the game?'

"And I said, 'Well, if we win we spray everybody with champagne.' And I could see him thinking. And the first thing he said to me when he came onto the field after the win, he said, 'Daddy we can do the champagne thing now!'

"We was in the locker room and I kept him right back out of the way because there was champagne flying everywhere, and I looked back to see if he was OK and was like that (with his moth open)."

David - who has recently been linked with a move to French team Paris Saint-Germain - hinted the match may have been his last for Los Angeles Galaxy.

He added: "We have had an amazing time living here in LA, and playing for the Galaxy and finishing it off like this.

"I am saying that because it is the last game of the season, it is the MLS final and it's the last game of my five year contract, but it doesn't mean that I am not staying here."
