David Beckham And Sons Romeo And Cruz Go Gold (Slimed)

David Beckham has never been afraid to make fun of himself, despite his fame and wealth – and now he's roped his sons into the fun, too.

Goldenballs, as he's affectionately known (by his wife) appeared on stage with sons Romeo and Cruz at a kids' sports award bash – and they all ended up covered from head to toe in GOLDEN GOO!

True to form, though, the Beckhams laughed it off (although Cruz looked a big miffed that his designer T-shirt had been ruined) and, actually, still managed to look rather stylish covered in the glop – like living Oscar statuettes!

The hilarious sliming happened at the Nickelodeon Kids' Choice Sports Awards in Los Angeles on Thursday.

The 39-year-old was unceremoniously covered in the sticky stuff as he took part in a skit onstage with his boys Romeo, 11, and Cruz, nine.

The retired midfielder was one boy short as he attended the popular children's event at the UCLA Pauley Pavilion.

It was the perfect opportunity for a boys only night out, with Romeo and Cruz having a great time as they hammed it up with their old man on the red carpet.

But David and Victoria's 15-year-old son Brooklyn was conspicuous by his absence as the trio posed in front of adoring fans.

Of course, we're used to seeing David make a show of himself in public.

How else can you explain a man approaching 40 constantly posing in his undies on giant posters?

When he was asked by a magazine whether he'll ever get used to seeing images of himself wearing next to nothing, the tongue-in-cheek star replied: "I don't think so. Especially not when I've got my mum calling me up saying, 'I've just seen another huge billboard of you in London – just you in your underwear'."
