Katy Perry's Left Shark Onesie

The 30-year-old singer was joined by backing dancers dressed as the killer fish, palm trees and beach balls for her rendition of 'California Gurls' and 'Teenage Dream' at her half-time show at the NFL final in February.

The dancing sharks attracted a lot of praise and attention on social media, and now Katy has released a "Left Shark belovesie" via her official online store (katyperry.shop.bravadousa.com).

Announcing the new product on Twitter, she posted: "ATTENTION INTERNET: NO LONGER DO YOU HAVE TO DIY LEFT SHARK COSTUME ... YOU CAN NOW BE A PROPER #LEFTSHARK WITH THIS OFFICIAL, GLORIOUS #LEFTSHARK ONESIE (sic)"

The pop superstar has also released a T-shirt emblazoned with a Left Shark, with the words "Current Mood" emblazoned across the front and "Katy Perry" and "#leftshark# on the back.

Following the reaction to the shark dancers in the wake of the Super Bowl show, Katy's boyfriend John Mayer claimed people said they liked the backing dancers because they were too embarrassed to admit her performance was "awesome".

He said: "I think the whole thing about the sharks, everybody wants to talk about the sharks because it's just something everyone can grab onto because not everyone feels comfortable walking around saying that Katy Perry was amazing."
