Brooklyn Beckham tries to play it cool on Instagram… until dad David ruins it (Pics)

Dads embarrass their sons - it is what they are meant to do.

Since time immemorial, young lads have attempted to navigate their way to full adulthood by playing it cool and putting on a veneer of aloof confidence to mask their insecurities. And for just as long, there's been an annoying dad about to nip any pretension firmly in the bud. David Beckham may be one of the coolest and most widely admired men on the planet but he's clearly no different. Young Brooklyn Beckham - now a strapping 16 years old - posted a snap on Instagram on Friday night, looking very cool indeed in a vintage Ralph Lauren top. With his eyes enigmatically closed shut, with a nice black and white filter, the description read: "Rocking the old school Ralph Lauren"... Brooklyn has developed something of an amorous following of young girls who quite fancy him in his own right. They were suitably swooning in their appreciation. All was going well until father David decided to pipe up in the most public way possible. "That's my jumper", he simply replied to his son's image. Way to harsh his chill, Dave...
