Singer/actress Ariana Grande has written a 'thank you' letter to the cast and crew of Sam & Cat following the cancellation of her hit U.S. Tv series.

The teen sitcom, starring Victorious' Grande and iCarly's Jennette MCCurdy, was put on hiatus in April (14) and now executives at the show's network Nickelodeon have announced the programme will not be returning for another season.

Sharing her thoughts on the end of the show, Grande took to Twitter.com on Sunday (13Jul14) to give thanks to those who have been involved with the series since its inception.

She wrote, "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 will always hold (character) Cat near and dear to my heart and appreciate her help in my personal growth from teenager to adult. I know she seems like a simple, daft character (and she is) but she played such a huge part in my life.

"Thank you to the cast and crew who I spent almost every day with for a good 4 or 5 years... The guys behind the scenes couldn't have been more pleasant or hard working and I appreciate them for that so much. I can't imagine that there is a more pleasant or professional crew in Hollywood.

"Thank you from the bottom of my heart to a true friend of mine, (series creator) Dan Schneider. I will never take these memories or lessons learned for granted.

"Lastly, thank you to my fans who have been with me since all of this started... you are the most loyal, dedicated and continuously loving supporters I could ever imagine. We've been through so much and you are still here... and we've got a long way to go. Thank you for believing in me, accepting me and loving me. I love you forever."
