Ariana Grande took to Instagram on Wednesday to confirm her appearance on Showtime's comedy-drama Kidding.

The 26-year-old singer announced her "tiny" cameo along with a heartfelt message to the show's star Jim Carrey.

"I’ve been staring at my screen and no words do this moment justice. Thankful for the most special experience of my life," she wrote in the caption. "Nothing is crazier than getting to work with and spend time with someone whom you've idolized and adored since before you could speak. Actually, what’s even crazier is discovering that person to be more special and warm and generous in person than you ever could’ve imagined. [...] Thank you thank you thank you Jim and thank you Dave [Holstein, the show's creator] for having me."
