Princess Claire and Prince Felix of Luxembourg's sweetest moments

A sunny date from the early days of their courtship.

The fresh-faced couple attending one of their earlier high-profile dates, a benefit gala in Miami in 2012.

Felix plants a gentle kiss on Claire's head as he presents his future bride to the world. The palace announced their engagement in December 2012.

The pair exchanged vows in the town of Königstein, near the bride's native Frankfurt. Their civil service was the first of two wedding ceremonies for the loved-up duo.

Now legally husband and wife, the royal duo prepare to drive off into married life in their cute 'just wed' car.

Their lavish religious wedding came next. Felix tied the knot with his German love in a beautiful ceremony that took place at the magnificent 13th century Sainte Marie-Madeleine basilica in the South of France in September 2013.

The couple's joy was clear for the world to see during their religious ceremony.

Felix fusses over their newborn as she meets the royal photographers for the first time. The couple were on their way home from the Grand-Duchesse Charlotte Maternity Wing at the Centre Hospitalier de Luxembourg with their daughter, who was just two days old.

The couple are full of joy as they leave the Saint Ferreol Chapel in Lorgues, France on July 12, 2014 after baptising their baby girl.

The trio are the picture-perfect royal family in a portrait released to mark Amalia's first birthday.

On July 4, 2016, the proud parents announced in an official statement that they are expecting their second child. The statement read: "Their royal highnesses the Grand-Duke and Grand-Duchess of Luxembourg are very pleased to announce that Prince Félix and Princess Claire are expecting their second child. The birth is expected to take place in autumn."

And then they were four! Prince Liam was born on Nov. 28 2016 in Geneva, Switzerland. Big sister Princess Amalia is clearly besotted with the new arrival, and can be seen doting on him in this sweet family photograph released by the palace.

It's clear to see how very much in love Princess Claire and Prince Felix are with each other. The royal sweethearts, who met at boarding school and went on to wed in 2013, are not shy about sharing loving looks or tender embraces.
The couple started a new chapter in their lives in 2014 when they became parents to daughter Princess Amalia. Then, just two years later they added Prince Liam to their growing family.
