Frankie Grande has claimed his sister Ariana outed him in a magazine interview.

The 33-year-old who is currently in the Celebrity Big Brother house made the revelation to former model Samantha Fox.

It came after he received a good luck message from singer and half-sister Ariana.

“I just wanted to say how much I love you and how proud I am of you. I’m proud of you for being yourself. I miss you so much and I can’t wait to see you. I have so much to tell you. I have so much music to play you,” she said.

Speaking to Fox, Frankie said Ariana just happened to mention that he was bullied at school for being gay.

“I was like, ‘thank you’ that was a weight off my chest,” he said.

Ariana previously revealed that she quit the Catholic Church after her gay brother was told “God doesn’t love you”.

Singer and former glamour model Samantha Fox previously opened up about her same-sex relationship with her late manager Myra Stratton.

Fox in August confirmed that her partner of over a decade, Myra Stratton, had passed away.
