But her relationship with Mario-Max, who is 14 years her senior, has drawn attention after the couple posted loved-up photos and videos of themselves on a Valentines trip to Paris before embarking on a Florida beach vacation in ritzy Palm Beach.

'Work hard, play hard! The beach was calling so we flew to paradise. Palm Beach won our hearts, and just like with us - it was Love at first sight!!!', Andrea Catsimatidis wrote on Instagram.

On Valentine's Day she expressed her love for Mario-Max once again as they celebrated five months together with a posting from Paris.

'We feel truly blessed to have found true love, it is everything we ever wanted and even more than we could have ever dreamed of. Every moment together, even the simplest ones, are filled with love, joy, and fun And the best is yet to come!!! Nothing beats the feeling of being with the love of my life, in the city of love!' Catsimatidis wrote.

The couple is currently in Palm Beach and posting all manner of cringeworthy videos to social media including standing in front of a private jet, to drawing hearts in the sand with their feet.

Mario-Max, 46, who has been has dubbed the 'King of Trash TV' by the German press has long claimed to have princely connections and is believed to have been adopted into the Schaumburg-Lippe family at the age of 24, and subsequently assumed his regal title.

Mario-Max's reps say the pair are both prepared to face whatever media attention may ensue, noting how the prince appreciates Catsimatidis intelligence, beauty, and ambitions. 

Mario-Max is a regular visitor to America, where he has posed for photos with celebrities including Paris Hilton, Liza Minnelli and Ivana Trump at parties and red-carpet events, but controversy recently swirled when he took a selfie with Prince Harry during an event in Los Angeles last month.

It led to the head of the royal household, Prince Alexander of Schaumburg-Lippe, accusing Mario-Max of 'harvesting our name for personal gain' and warning Prince Harry to 'stay away from this man'.

'It's very painful for me, this guy has been harvesting our name for his personal gain. Prince Harry cannot stoop lower than appearing with him. I would advise him to stay away from this man,' he said.

The head of the family, Prince Alexander of Schaumburg-Lippe, said Harry 'could not stoop any lower' than appearing with Prince Mario-Max

Speaking about meeting Harry, Mario-Max told the Daily Mail: 'We had a personal conversation and he was fabulous, very humble, very sweet. It filled me with joy.'

Critics, including Prince Harry's biographer, have questioned the prince's credibility, suggesting that his reality TV background may compromise the legitimacy of his claims.

But despite the trappings of wealth, there appears to be no depths to which Mario-Max will not sink for pure publicity or for a few more followers on his social media accounts.

In 2014, he appeared on the German version of Celebrity Big Brother where he was evicted after just eight days inside the house, as well as appearing on a shopping channel to sell a 'wealth elixir' at 99 euros for a 56ml bottle. 

Other embarrassing stunts include semi-naked modeling of lederhosen-style swimming trunks. 

He also has a penchant for asking rich and famous people for selfies to post to his 43,000 followers including Prince Albert of Monaco, Lady Gaga, Emily Blunt, Andrew Lloyd Webber and Paris Hilton.

Marios-Max has also had cameos on The Real Housewives of Beverly Hills when he dated one of the stars and Bravo’s Millionaire Matchmaker when he went in search of a wife in Iowa. 

His reps have defended his use of his royal title stressing that should the prince and Catsimatidis have children, they would also inherit royal titles.

Mario-Max's website boasts of family connections stretching back to William of Orange, which would make him a very, very distant cousin of the British Royals including Harry. 

He even shared his birth certificate online to back his claims that he is the son of a prince and princess with links to royal houses in Germany and Denmark. 

The 'prince' also presents a royal show called 'Astro Royal' from Berlin that is broadcast on cable, satellite and web-tv. He also says in his Instagram profile that he is a journalist.
