Nickelodeon's very successful teen-series Sam & Cat has been officially cancelled.

A network spokesperson confirmed the news in a statement: "Nickelodeon will not be producing more episodes of Sam & Cat. We are very proud of the show and its very talented cast and we wish them all the best."

Ariana Grande took to her Facebook and Twitter accounts to thank the fans of the show, series creator Dan Schneider and the cast and crew.

"I want to thank Nickelodeon for making a childhood dream of mine come true, for being a family to me, for being so accommodating and supportive of my multitasking with my music career, and for of course introducing me to many of my fans however many years ago. I want to thank Dan Schneider (@DanWarp) for allowing me to play such a special, beautiful character who I hid behind for so long. What I mean by that is when I was younger, people loved Cat so much I used to pretend to be more like her," she wrote.

The show that premiered last year in June, has consistently been one of the cable channel's highest rated shows.

Rumours of the show's end began in April, when Jennette McCurdy didn't show up at the Nickelodeon Kids' Choice Awards and even unfollowed Grande on Twitter.

The 22-year-old was allegedly upset with Nickelodeon because Grande was paid more salary than her.

Sam & Cat will air its final episode on 17 July.
