The Best Song Ever hitmaker appealed to fans at the Qualcomm Stadium gig, not far from the city's SeaWorld resort, to boycott the parks amid concerns of the mistreatment of animals kept in captivity, stating, "Does anybody like dolphins? Don't go to SeaWorld."

Video footage of Styles' simple statement was shared online by fans and fellow animal rights activists, including officials at People for the Ethical Treatment of Animals (PETA) and Game of Thrones actress Maisie Williams, who tweeted, "You heard him ladies and gents. Don't go to sea world (sic)."

However, SeaWorld chiefs are seeking to change the British singer's opinion of their parks by inviting him to a special visit.

A representative writes on Twitter.com, "@Harry_Styles, if you want to see what SeaWorld is really about, we're happy to show you and answer your questions."

The post also links to an open letter to Styles, which reads: "We've seen a concert clip of you urging your fans not to visit SeaWorld. We want you to know we love dolphins too. We care for the animals in our parks like we would our own family. We are committed to making sure their lives are enriching and they are continually engaged socially, mentally and physically. And, we also care for dolphins in the wild...

"We invite you to see for yourself, and then decide based on facts. We are happy to open our doors, take you behind the scenes, and have our trainers and vets answer any questions you have."

Styles has yet to respond to the offer.
