Russian synchronized swimming champions Vlada Chigireva and Maria Shurochkina made a splash on Instagram on Saturday as they dressed up as the Joker and Harley Quinn for Halloween.

Chigireva – who donned Harley’s iconic makeup and pigtails to achieve the look – posted a video of herself and Shurochkina at the beach clad in bikinis.

The pair blow kisses at the camera and proceed to dive into the water, before a smash cut to them emerging from the sea as the comic book characters, with Shurochkina laughing suitably maniacally to fit her role as the Joker.

The video is set to a version of “Rock and Roll Part 2,” a song by Gary Glitter which features in an iconic scene from the 2019 film Joker, in which the character dances down a staircase.

Shurochkina also posted a similar solo video on her own Instagram feed, in which she also showed off her acrobatic skills with some cartwheels along the beach.

Russia’s synchronized swimmers – known as the ‘mermaids’ – have been attending a training camp in the UAE.

The team has not been defeated on the international stage in over 20 years, since claiming victory at the Sydney Olympics in 2000.
