Katy Perry has thanked 'Left Shark' for her Emmy nomination.

The 'Dark Horse' hitmaker has praised the dancing shark which joined her on stage during her Super Bowl XLIX halftime performance after she was nominated in the Outstanding Short-Format Live-Action Entertainment Program category at the Emmy Awards.

She wrote on Twitter: ''Um...Woke up to my first Emmy nomination for the Halftime show!!! V proud of everyone involved especially #leftshark (sic).''

The 30-year-old star was joined on stage by two backup dancers in shark costumes during one segment of the show with the groover to the singer's left entertaining fans across the world with his hilarious moves.

The 'Left Shark' has since become an internet sensation, with Katy now even selling merchandise linked to the character, although her choreographer RJ Durell previously admitted the funny dance moves were all part of their plan for the performance.

He explained: ''The sharks were given two main objectives.

''One, perform Katy's trademark moves to the 'Teenage Dream' chorus, which they both did perfectly; and two, to have loads of fun, and bring to life these characters in a cartoon manner, giving them a Tweedledee/Tweedledum-type persona.

''Clearly, that was portrayed with the overzealous shark on the right hitting precise dance moves, while the left shark was playing up the more goofy, fun-spirited sports-fan mascot type, who was just happy to be at the Super Bowl.''
