We've been worried about the state of Ariana Grande and Jennette McCurdy's hit show ever since Jennette skipped out on the Kids Choice Awards, but Nickelodeon has confirmed that it's official — Sam & Cat is over for good. The final episode will air on July 17th.

Nickelodeon didn't offer any details about the cancellation, merely saying, "We are very proud of the show and its very talented cast and we wish them all the best."

While Jennette hasn't commented on the show's end yet — even though she's been online, posting selfies on Instagram — Ariana wrote a long message on her Facebook and Twitter accounts expressing her gratitude for the show and its creator.

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

However, in Ariana's 750-word response, she never once mentions Jennette or her character, which makes us think that there might still be tension between the two costars — Jennette and Ariana currently aren't following each other on Twitter.

She continued, "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."

Could that be a subtle jab at Jennette's professionalism? Ariana also posted a cryptic tweet about a "spontaneous tweet attack" from an unnamed someone.

We know that Jennette has publicly blasted one of her friends on Twitter before, so we're wondering if Ariana's tweet has something to do with Jennette. Sounds like there's still some more drama!
