Frankie Grande is "definitely" in his sister Ariana's bridal party and thinks he will be "gay of honour" when she weds.
The 'No Tears Left To Cry' hitmaker got engaged to Pete Davidson earlier this year after just a few weeks of dating and she's promised her 35-year-old sibling, Frankie Grande, a key role in her bridal party.
The former 'Big Brother' star gushed: "Oh, my god. It's not like 'Big Brother'! It's a very exciting, wonderful, joyous celebration. It's not stressful like being locked in a house with 16 houseguests!
"I'm just so excited that we get to have this amazing celebration and I get to be a part of it, obviously.
"I'm excited. I'm excited for her and I'm excited for Pete. I think it's going to be wonderful.
"I'm definitely in the bridal party. We're sorting out everything as of now, but I'll definitely be the 'gay of honour.'"
And Frankie definitely approves of his 25-year-old sister's fiance.
Speaking on the red carpet at the MTV Video Music Awards at Radio City Music Hall in New York on Monday (20.08.18), he told 'Entertainment Tonight': "Listen, my sister's super happy, so I approve. As long as she's happy, then I approve."
The flamboyant reality star is a big fan of Ariana's music and particularly loves the "sexy" songs on her latest album, 'Sweetener'.
He said: "Girl, we've had 'Love Me Harder.' There's been a lot of sexy music coming from my sister, and we're very Italian, we're a very passionate family, so of course I approve. More! More passion!
"[The] 'Sweetener' release party was super extra, so we're just dancing, living our lives and having the best time. It's such a good album."
