James Van Der Beek's 4 Little Kids Reenact His DWTS Pirate Performance in a New Home Video

James Van Der Beek's children reenacted their father's pirate performance on DWTS, and it's hilarious and adorable.

James Van Der Beek's children are closely following his performances on "Dancing with the Stars," and reenacted his latest performance on the dance competition.

The actor's children, Olivia, Joshua, Annabel, and Emilia, aged between 9 and 3, reenacted their father's pirate performance in a home video shared on James' Instagram.

In it, the younger girls, wearing tutu skirts paired with each other, with the older children doing the same.

Their mom, Kimberly, played the soundtrack from the "Pirates of the Caribbean" movie, and her children danced with arm and leg movements.

At one point, Joshua said to the actor's wife, "Mom make sure you get me," and she responded, "I gotcha."

In the accompanying caption, James acknowledging his children's attempt wrote, "What you do with all your heart can be contagious," with a heart-shaped emoji.

The "Dawson Creek" star's followers appeared to agree with him, and his DWTS dance partner, Emma Slate, commented,

"Omg! I am obsessed. They are adorable."

One follower wrote, "Children are great imitators, so give them something great to imitate. [A] perfect example is this," while another commented, "You and your family are incredible."

James gave the pirate-themed performance during last week's Disney Night on DWTS. The actor and his partner performed the Paso Doble set to "He's a Pirate," by Klaus Badelt; the song formed part of the soundtrack for "Pirates of the Caribbean: The Curse of the Black Pearl."

The actor and Slate scored two 9s and an 8 for their performance. Since joining DWTS, the "Pose" star has impressed the judges and fans with his performance, but beyond the show, he has a lot going for him.

James, who also shares, 16-month-old Gwendolyn, with Kimberly, is expecting his sixth child.

In an Instagram post, the actor revealed that the cameras of the ABC show filmed his wife's first ultrasound, and he is beyond happy to share the news with everyone, and grateful because the baby chose his family.

DWTS airs on Monday nights by 8 p.m. ET on ABC.
