Victoria Beckham's swaps her figure-hugging dresses and high heels for a bikini top and a mermaid tail in her highly-anticipated cameo on SpongeBob SquarePants.
The former Spice Girl voices her animated alter-ego Queen Amphitrite for the 30-minute special, The Clash Of Triton.
"I was so thrilled when I was asked to be a part of SpongeBob as my children love the show - when I told the boys that I was going to be on the show, they were so excited!" she gushed.
"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 Queen aims to give husband King Neptune's (voiced by Seinfeld's John O'Hurley) a 5,000th birthday he won't forget in the episode, but their son Triton (Sebastian Bach, former Skid Row frontman) attempts to put a spanner in the celebrations.
Victoria follows in the star-studded footsteps of Johnny Depp, Scarlett Johansson and David Bowie by appearing in the hit cartoon.
:: Victoria's appearance on SpongeBob SquarePants can be seen on November 15 at 4.30pm on Nickelodeon and NickToons.
