Victoria Beckham is to star as Bikini Bottom's Queen in a special celebrity episode of Spongebob Squarepants.
The wife of footie legend David Beckham plays the part of mermaid Queen Amphitrite in the 30-minute special, called The Clash of Triton.
Posh said she was thrilled to be asked to take part in the show as her three sons love watching it.
"When I told the boys that I was going to be on the show, they were so excited," she said.
"I had such a great time recording the voice of Queen Amphitrite. How fun to be a Queen for a day!
"We are all looking forward to watching it together."
The episode is due to be shown in America on 5 July, but a release date for the UK hasn't been announced yet.
