Beyonce donned Pamela Anderson’s red Baywatch swimsuit as she encouraged US citizens to go out to vote in the American presidential election.

The US singer, who backed Kamala Harris in the race to the White House before the polls opened on Tuesday, posted a rare music video to her Cowboy Carter single Bodyguard.

The clip, titled Beywatch, takes its name from the lifeguard series starring Anderson and shows 43-year-old Beyonce holding a toy gun with a flag saying “vote”.

She also appears to be wearing the black sleek clothes, a nod to Barb Wire, which Anderson wore when she played the superhero during the 1996 film of the same name.

Anderson shared an Instagram story of the post, with a love heart emoji, and joked “Don’t call me Bey”.

Beyonce has previously told GQ magazine that she did not make music videos for Renaissance or Cowboy Carter as she sees them as a “distraction from the quality of the voice and the music”.

The new two-and-a-half-minute clip also made reference to Halloween with white text at the end saying “Happy Beylloween” then “Vote”.

Eminem, Taylor Swift and Bruce Springsteen are among the celebrities who have backed Ms Harris, the Democrat nominee and current vice president.

Beyonce appeared at a rally for Ms Harris last month and told the audience: “For all the men and women in this room, and watching around the country, we need you.”

She added she was “here as a mother,” to talk about how her children would see “the sacrifices made so we can witness the strength of a woman … reimagining what leadership is”.
