“Scream Queens” actress Lea Michele loved Ariana Grande’s performance at the 2016 iHeartRadio Music Festival on Saturday night, Sept. 24.

Michele took to Twitter the following day to commend Grande’s song and dance number at the annual music festival held at T-Mobile Arena in Las Vegas, Nev. “This girl was amazing last night! Love you @ArianaGrande,” Michele tweeted, along with a video of Grande performing her song “Side to Side” onstage.

Michele has been a fan of the 23-year-old pop star for a long time now. After the Television Critics Association summer press day in August 2015, the 30-year-old “Glee” alum said in an interview that Grande’s acting and singing really impressed her.

“Ari’s so fun, and it’s so great having her,” Michele said of the former Nickelodeon star. “She’s an actress. She’s an incredible singer, but she’s a great actress. I had to do this hilarious scene with her the other day [on ‘Scream Queens’] and we were just cracking up.”

When asked if she would like to collaborate with Grande in the future. Michele said: “Oh my god, I want to sing with her so bad, maybe in a concert!”

Grande played Chanel #2 in Season 1 of “Scream Queens,” where she and Michele — who plays Hester on the series — got closer.

“Scream Queens” Season 2, episode 2, titled “Warts and All,” airs on Tuesday, Sept. 27, at 9 p.m. on FOX. Check out the synopsis for the episode below:

“A new patient (Colton Haynes) with a hideous ailment visits the hospital in hope of a cure, but finds a love interest instead. Meanwhile, Chad (Glen Powell) returns to win Chanel (Emma Roberts) back and, in the process, discovers a dark secret of Dr. Holt’s (John Stamos). Then, after another run-in with the killer, Munsch (Jamie Lee Curtis) enlists the help of new Quantico special agent Denise Hemphill (Niecy Nash).”
