Princess Tatiana of Greece makes her first public appearance since split from Prince Nikolaos was announced - and is joined by his mother Queen Anne-Marie

Princess Tatiana of Greece looked in high spirits as she attended an Olympic Handover ceremony with her mother-in-law after her separation announcement. 

The Greek royal, 43, cut an elegant figure as she opted to don a vibrant sapphire-blue matching ensemble whilst accompanying Queen Anne-Marie, 77, to the event on 26 April. 

After almost 14 years of marriage, Princess Tatiana and Prince Nikolaos shocked royal fans when they unexpectedly announced their separation on April 19. 

Prince Nikolaos' mother, Queen Anne-Marie, sat next to her husband's estranged wife as the pair arrived together at the Panathenaic Stadium in Athens. 

According to HELLO! Greece, Venezuela-born Tatiana will keep her Princess title after the divorce, although given the Greek monarchy has been defunct since 1967, it carries social prestige rather than any constitutional meaning.

Tatiana grinned as she put her best fashion foot forward in a patterned in blouse and flare trouser co-ord and tan-coloured heels. 

She opted for stylish accessories, such as a patterned white box-clutch bag and a gold necklace with matching dangly earrings. 

The royal opted for smoky eye makeup, with eyeliner, sparkly eye-shadow and mascara with a hint of lip gloss.  She also let her blonde tresses hang loose in a chic, wavy blowdry.

Queen Anne-Marie, who is the widow of the late Constantine II, sported a monochrome polka dot dress and a cream jacket. 

The pair were pictured chatting away as they watched the historic event unfold at the first modern Olympic stadium in the world. 

The outing, which came just one week after the announcement, saw honoured quests of the Hellenic Olympic Committee signify the handover from Greece to France. 

Greek Olympian Antigoni Ntrismpioti passed the iconic flame to the French Olympic gold and silver medallist in figure skating, Gabriella Papadakis. 

She then gave to France's multiple Paralympic swimming gold medallist Béatrice Hess.

Prince Nikolaos married Venezuelan-born Princess Tatiana, 43, in August 2010, and the pair had only been pictured together at a thanksgiving service for his father in Windsor in February. Constantine died in Athens last year of a stroke at the age of 82. 

The wedding - which was described as 'Mamma Mia, but with aristocrats' - was attended by royalty from around the world, including monarchies from the Netherlands, Denmark, Sweden and Spain.

In a statement put out on the Greek royal family's website, it stated: After fourteen years of marriage, [Tatiana and Nikolaos] have chosen to amicably dissolve their union. 

'This decision was reached with great care and mutual respect, reflecting the depth of their appreciation for one another and the moments they have shared. 

'Their future interactions will continue to be guided by these same principles of respect and understanding, as they transition into a relationship rooted in a strong friendship. 

'They will continue to live and build their lives in Greece, a place they both call home. The Family will always support them.'

Down-to-earth Tatiana already seemed at odds with the extravagance of Greek royal life, asking the nobles and princes present to trade their formal wear for caftans and sandals. 

Shortly after her wedding, she admitted: 'I do not feel like a princess. I do not feel that I married a prince, with a title. Well actually, yes, he is my prince, but nothing more.' 

Tatiana was born in Venezuelan capital Caracas and went to boarding school in Switzerland before studying sociology at Georgetown.

The couple met during a ski holiday in Switzerland in 2003 and announced their engagement six years later - with the wedding one of the high society events of the year.

Shortly after their wedding, Princess Tatiana left her job as an events' organiser for designer Diana Von Furstenberg, MailOnline previously reported. 

She lived in Chelsea in London and visited Greece with Nikalaos for the first time in 2004, before moving there permanently in 2013.

Nikalaos, who was raised in Britain, had always dreamed of living in Greece, but his wife didn't feel the same way.

The aristocrat didn't speak any Greek, and told Vogue about her feelings on arriving into the country - which already hinted at how uncomfortable she was.

She told the fashion magazine: 'I remember when we drove in, it felt like everyone was traveling in the opposite direction.' 

The wedding, on the island of Spetses, Greece, was a high society event of the year attended by royal dignitaries from across Europe

 In the same interview, she revealed that her new royal life was rather different to how you might expect.

She continued: 'I live a very simple life here. I work, I go to the supermarket, I cook, I walk my dog, and the Greek people have welcomed me like they would anyone else.' 

Greek media has reported murmurs of estrangement in recent months - with the appearance at the Windsor memorial service in February the last time they were seen together in public. 

The couple do not have any children. Prince Nikolaos is the third child of King Constantine II, Greece's last reigning monarch, who passed away on January 10 last year after suffering a stroke.
