Kate Middleton's unicorn name has been revealed.

On Tuesday, Middleton's mom, Carole Middleton, shared a post on Party Piece's Facebook page to teach her followers how to find their unicorn name. "What's your Unicorn name? Let us know what you get in the comments! *closes eyes and hopes for someone to be a 'Classy Marshmallow Moon,'" the caption read.

Based on the post, the Duchess of Cambridge's unicorn name is Clever Twinkle Toes if she uses her first name, Catherine. If she uses Kate, then her unicorn name is Giddy Twinkle Toes.

According to People, there are a lot of reasons that the Duchess of Cambridge should be giddy these days. For instance, she and Prince William are expecting their third baby in April. In addition, Princess Charlotte just attended her first day of nursery school. Middleton also turned 36 on Tuesday.

The royal couple is aware of the good things they are enjoying. In fact, earlier this month, Prince William and Middleton released a thank you Christmas card for their followers. It included a family portrait that was taken at the Trooping the Colour in June 2017.

"The Duke and Duchess of Cambridge, Prince George and Princess Charlotte are most grateful for the kind message you so thoughtfully sent for Christmas. Their Royal Highnesses send you their warmest thanks, with very best wishes for Christmas and for the New Year," the message read.

As for Middleton's "twinkle toes," Middleton has already proven this when she danced with Paddington Bear at the Paddington Station in London in October. Prince William laughed and watched his wife as Middleton showcased her dancing skills by twirling around the mascot.

In related news, Middleton was spotted with Prince William and Prince Charles just days before her birthday. The trio walked to St. Mary Magdalene Church in Sandringham to attend the Sunday service. Queen Elizabeth II reportedly attended the same service but opted to drive instead of walk.

During the sighting, Middleton recycled her military-style jacket that she wore in 2014. She paired it with a brown fur trim hat and matching gloves. The Duchess of Cambridge has used the same items during multiple occasions.
