Prince Albert’s eldest child Jazmin Grimaldi has marked her brother’s 20th birthday by sharing sweet snaps of the siblings together when they were younger.
Alexandre Grimaldi-Coste celebrated with a family meal – which was attended by his father Prince Albert, mother Nicole Coste and half-sister Jazmin.
Jazmin posted pictures on Instagram from when the two were younger, with one image showing Alexandre posing in an F.C Barcelona football shirt.
She captioned the images: ’10 years have flown by… Happy 20th Birthday to the most amazing little brother a big sister could ask for. Love you bro!’
Jazmin, 31, is Prince Albert of Monaco’s daughter and oldest child, who he shares with American Tamara Rotolo.
His half-sister Jazmin Grace Grimaldi, who was also at the meal, posted a picture of them both when they were younger, with Alexandre sporting an F.C Barcelona football shirt
She also later shared a picture on her Instagram stories of his birthday cake, which featured layers of cream and fruit, tagging Alexandre’s account in her post.
It comes as Alexandre’s mother Nicole Coste, 51, also posted some pictures of his birthday on the social media platform.
One of the snaps shows Prince Albert, 65, sitting in between his eldest son and his smiling ex-lover, Nicole.
The family gathered to share an intimate meal together outside, surrounded by greenery.
The former flight attendant from Togo wrote: ‘Happy birthday Alexandre,’ adding a love heart emoji to the caption.
However, the royal’s wife Princess Charlene, 45, was nowhere to be seen.
They also indulged in a second birthday cake which was red and white, for the flag of Monaco and said ‘Happy Birthday Alexandre, 20 years.’ It also featured the Coat of arms of Monaco.
Although he is Albert’s eldest son, he is not in the line of succession to the Monégasques throne as his parents were not married when he was born.

The royal also has his twins Prince Jacques and Princess Gabriella, eight, who he shares with wife Princess Charlene.
As Prince Jacques is Albert’s ‘legitimate’ child (because he was born when he was married to Charlene), he is the current heir to the Monegasque throne.
Alexandre recently hit out at trolls who have called him illegitimate and said he found it ‘insulting’, because his parents ‘did not commit adultery’.
The university student, who studies business and management in the UK, gave a tell-all interview to French magazine Point de Vue ahead of his birthday, where he described father Prince Albert of Monaco, 65, as ‘benevolent’ and said he considers himself ‘lucky’.
His father acknowledged his paternity as an infant, and despite growing up out of the spotlight he has increasingly come into the royal fold in recent years.
Since 2022, with his father’s encouragement, he has begun using his family’s name of Grimaldi (although kept his mother’s too, with the hyphenated with Grimaldi-Coste).
‘My father’s name is Grimaldi. It makes sense that I bear his name. I would have been called Dochomel if my father had been Mr. Dochomel!’ he told the magazine.’
He also hit back at being called ‘illegitimate’ complaining that online trolls question his legitimacy.
‘When I was born, neither of my parents were in another marriage, and they did not commit adultery. Using that word [illegitimate] is insulting!

‘I hope no one believes the lies conveyed on the internet. One bears the name of one’s father when one has been recognised since birth. I had voluntary recognition from my father when I was a baby. Not from a judge or the press who have forced him to,’ he added.
‘My mother, whom I adore is my rock, and she is not jealous at all of my choice. If she never said anything about my surname, it’s been to protect our privacy. I was two years old when I was revealed in the press.’
Alexandre, who studies Business Management and English, added that he lives with his mother and two older half-brothers from her previous marriage.
‘Jazmin is my big sister, and I love her like I love my two big brothers on my mother’s side,’ Alexandre added.
‘We all get along very well, and Jazmin is also very close to one of my two brothers with whom she shares the same birthday. We’ve a good relationship despite the fact that we live in distant countries.’
He also joked that he has a ‘tenderness’ with his younger siblings – but doesn’t ‘share their toys’ because of the age difference.

The royal has spent time with the Monegasque side of his family, and was recently pictured at his cousin, Louis Ducruet’s wedding.
Meanwhile, Princess Stephanie, his aunt, is also his godmother.
And despite his good looks, he said he has no plans to go into modelling, following his grandmother Grace Kelly’s footsteps.
‘My father is a prince and head of state — I personally cannot imagine myself marching on a podium.’
‘On the other hand, if a prestigious brand asks me to be its ambassador and its image suits me, why not?’
