AceShowbiz - Ariana Grande's big brother is backtracking after appearing to confirm the pop star's romance with Social House star Mikey Foster.
Frankie Grande gushed about the man who reportedly has his sister's heart at a red carpet event on Wednesday night, September 04, revealing he's a big fan.
"I love Mikey," he told Us. "I think he's a really sweet guy. So talented. So kind and so caring. He's a great guy."
Frankie also revealed he and his boyfriend Hale Leon enjoyed a double date with Ariana and Foster, further appearing to confirm the rumoured romance.
But after his comments made headline news, Frankie took to Twitter on Thursday to end the fuss, writing, "My sister is not in a relationship. Everyone relax. She is very much single."
Ariana previously toured with Foster and his group and they teamed up in the studio to record summer hit "Boyfriend".
She has been single since ending her engagement to Pete Davidson last year (18).
