Frankie Grande Supports Sister Ariana from Abroad: 'Keep on Breathin' — That's True'

With her recent split from fiancé Pete Davidson and the death of her longtime boyfriend Mac Miller in September, it’s been a rough few weeks for Ariana Grande. Thankfully, her older brother has her back.

Frankie Grande posted a sweet message to the singer to his Instagram Story on Monday, sending her love and strength from across the seas as he vacations in Iceland.

“Good morning to my beautiful, beautiful sister. I love you so much and you’re with me right now in Iceland. Listen!” he began before singing the chorus to Ari’s Sweetener track, “Breathin’.”

“You know, you gotta keep on breathin’ — that’s true,” added the 35-year-old personality.
