Clearly enjoying his celebrations in honor of his 10 years as Monaco's monarch, Prince Albert got to his feet and danced alongside his wife throughout the evening. He was not the only one who enjoyed the concert; Robbie later tweeted his thanks to the royal couple on behalf of himself and his wife Ayda.

"Congratulations Prince Albert & Princess Charlene: thank you for having us, what a magical evening @GrimaldiPrince", he tweeted.

The concert capped off a weekend of celebrations held in Prince Albert's honor. On Saturday, Princess Charlene showed her support for her husband of four years by taking to the stage to give a speech in French, in which she declared that Albert is "the Prince of Hearts, of my heart".

The 57-year-old was visibly moved by his wife's loving words and embraced her on stage before giving his own address to the crowd. Charlene and Albert's young twins Prince Jacques and Princess Gabriella unknowingly stole the show throughout the address when they were spotted observing the action from a balcony in the arms of their nannies.
