Princess Charlene of Monaco (in a low-cut dress) and Prince Albert II attended the Christmas ball.

The 20th annual Charity Christmas Ball, hosted by Princess Charlene, was held at the Hotel de Paris in Monte Carlo. The 47-year-old princess attended the event with her husband, Prince Albert II of Monaco.

For the evening out, Charlene chose a white cape dress with a low neckline and a gold belt, completing the look with diamond earrings. Albert II wore a classic tuxedo with a bow tie. The evening included an auction organized by Sotheby's, the proceeds of which will be donated to the Princess of Monaco Children's Charity Fund.

Earlier, Princess Charlene and 67-year-old Prince Albert II, who have been married since 2011, along with their 10-year-old children, Crown Prince Jacques and Princess Gabriella, lit the Christmas tree in Monaco.

Let us recall that Grace Kelly's son, Prince Albert, has two more officially recognized illegitimate older children from different mothers who have no right to the throne.
