Princess Charlene is a scarlet siren in gorgeous form-fitting gown

Prince Albert II of Monaco's wife Princess Charlene was a total vision in red for a special event at the Prince's Palace on Saturday evening.

The royals held a dinner for France's President, Emmanuel Macron and his wife, Brigitte ahead of the UN Ocean Conference, but it was one red dress that stole the show…

The 47-year-old was pictured with her husband ahead of the president's arrival, waiting for him on the red carpet.

 The royal stepped out in a figure-skimming red dress with simplistic crew neck, no sleeves and a beautiful full skirt. The royal looked utterly stunning!

Alongside Charlene, her husband wore a smart black tuxedo, looking perfectly polished for the important occasion.

Perhaps the royal knows red is her colour as last month when visiting the Grand Prix she stepped out head to toe in the striking hue. Princess Charlene opted for a red blouse from Louis Vuitton, a pair of bright red high-rise tapered trousers, and red suede heels from Manolo Blahnik. She showed us exactly how mono-colour dressing should be done.

When the president first arrived in town, it was Albert and Charlene's children who stole the show.

Prince Jacques and Princess Gabriella were pictured greeting the VIP guests – and it was adorable.

Gabriella, could be seen clutching a small bouquet of bright flowers, which she presented to Brigitte upon her arrival.

After the official photos were taken, Brigitte was seen thanking Gabriella for the flowers and putting her arm around the young royal.

On Sunday, Prince Albert attended the Blue Economy and Finance Forum where he was pictured alongside Prince William before the British royal made a special speech, even attempting some in French!

The royal decided to address the room in French for the beginning and end of his speech, which translated to: Hello. It's a pleasure to be with you today to discuss an important topic that is close to my heart." and then: "Thank you again for having me here today. Now it's time to take action. Have a great afternoon. Thank you."
