Monaco's Charlotte Casiraghi has split from Gad Elmaleh.
The eighth-in-line to the throne has reportedly called time on her three year romance with comedian-actor Gad - with whom she has a 17-month-old son Raphael - after the couples' careers caused them to grow apart.
A source told PEOPLE: "It's sad. Mostly, this is a couple that drifted apart over their careers.He wasn't around enough - and she wanted a father for her son."
Charlotte - whose grandmother was the late Princess and actress Grace Kelly - met Gad, 44, at a party in 2011 and had sought to keep their relationship as private as possible ever since.
The couple made their first public appearance in 2013 at the Bal de la Rose and are thought to have split their time between living in France and LA.
Meanwhile, Charlotte - who is also a professional show jumper - was reported to have injured her back as she fell from her horse as she prepared to compete at the Saint Tropez Athina Onassis Horse Show after news of their split broke yesterday (05.06.15).
