David Beckham smiles alongside underwear snap as boozing with Cruz ends in sweet moment

David Beckham appeared particularly pleased with himself as he posed with a pint - featuring an underwear snap of himself. The former Manchester United and England legend is continuing to help his son, Cruz, celebrate his 18th birthday as they both made a trip to Dublin.

The father-and-son jetted off to the Emerald Isle and were seen hitting up one of Dublin's most famous pubs as they sank pints and listened to the musical offerings the city had to offer. The pair also popped into the Guinness Storehouse during their visit to the Irish capital where they got to pull their own pints of Guinness before sipping on their own personalised versions of the beverage.

Taking to his Instagram Story, David, 47, shared a snap of himself giving a smile to the camera as he held up his famous Irish stout with a photo of himself topless and in a tight pair of Armani briefs from a previous photoshoot.
