The Irish super-wealthy have spent their money on yachts, international properties and flash cars and perhaps are only outdone by their 'rich kids', the new generation of Irish movers and shakers.

Their parents may have enjoyed their riches in private, but the Irish rich kids' love of social media has given us a glimpse of how the other half lives.

Alexander Smurfit, the handsome son of the multi-millionaire packaging tycoon Michael has become an internet sensation thanks to his love of the high life. Never one to shy from the camera, he treats followers to videos of himself performing pull-ups on board a luxury yacht and getting massages after meals in St Barts - "to help digestion", of course.

Along with his presenter and model wife Victoria Bonya, he fills the public in on the most intimate moments of his day. Whether it's the mundane (low carb meals and gruelling workouts) or the magic (kicking back on a private jet, hitting golf balls into the ocean from a superyacht in St Tropez or skiing in Courchevel), the young Smurfit rarely takes a breather from making the most of his gilded life.

Not as brash with their postings are Bono's children, Jordan and Memphis Eve Hewson. Jordan has proven herself a feminist and political activist, supporting former US presidential candidate Hillary Clinton on the campaign trail and then taking to the Women's March protest at Trump Tower. In her downtime, she can be seen swimming with sharks, scuba-diving and vacationing in hot spots from Jordan to the Hamptons.

Her sister Eve sticks to detailing her nights out with non-celebrity friends and posting the odd family photograph. Not one to take her privileged life too seriously - she once took to Instagram to point out in a paparazzi shot how she loves to embarrass her famous father.

Another social media fan who has the world as her playground is Danielle Ryan, granddaughter of the late airline boss Tony. Whether it's shopping in Los Angeles' food markets to checking out the latest wardrobe staples at London Fashion Week and dining in Roberto Cavalli's restaurant in Ibiza, the CEO of international lifestyle brand Roads keeps followers captivated with her travels.

Chris de Burgh's daughter Rosanna Davison is another smart woman who has managed to make a business off the back of her online following. The shrewd operator has amassed almost 135,000 followers thanks to her updates on her diet and fitness plan. When she's not telling followers about her regime, she's enjoying annual family trips to Mauritius and, more recently, the Maldives.

Zak Jordan, son of Formula One legend Eddie, has proven to be every bit of a party-lover as his father. His photos in a hot tub on board a yacht in Monaco, relaxing in an infinity pool or on the ski lifts of Avoriaz, shows how the young racing heir is keeping alive the family tradition of living life in the fast lane. His bond with his dad is touching. The pair enjoy a diverse social life together - from days out at Stamford Bridge, Chelsea's football stadium, to fashion shows.

Let's hope the racing boss knows there are photos of him in strawberry-covered speedos out there thanks to Zak's social media postings.
