After a month of romance speculation surrounding Ariana Grande and Mikey Foster, did the songstress' brother Frankie Grande set the record straight?

Appearing at The Game Changers premiere on Wednesday in Los Angeles, Frankie dished to reporters about a recent "double date" he went on with his sister and Foster, according to Us Weekly.

"It was really fun," Frankie said, according to the magazine. "Game night! Board games! So fun."

Plus, it sounds like the Social House singer already has Frankie's stamp of approval. "I love Mikey. I think he's a really sweet guy. So talented. So kind and so caring," he reportedly said at the event. "He's a great guy."

Despite what Frankie reportedly said, sources confirmed to E! News Grande is single.
