His sister is one of the biggest names in music… now it’s his turn

Famous folk often have a less famous sibling lurking in the wings, waiting patiently for their own moment in the spotlight.

There's a Solange Knowles for every Beyonce; a Monica Cruz for each Penelope. 

Jennifer Lopez has Lynda (or Li-Lo, if you will), while Jessica Alba is sister to Joshua – an actor who's starred in TV dramas Dark Angel, and Monk (what, you've never heard of him?).

And now it has emerged that superstar singer-of-the-moment Ariana Grande has Frankie – her 32-year-old brother who's already made a name for himself as a YouTube sensation. 

He's furthermore appeared on Broadway in productions of Mamma Mia! and Rock Of Ages, and last year was a contestant on the US version of Big Brother.

But he's decided to take it up a notch – embarking on his very own tour.

"I am so excited about this tour because I get to bring all the insanity, glitter and excitement that makes my life so GRANDE to my fans all over the country," Frankie told PEOPLE. 

"I can't wait to take the audience on this journey. I live a crazy life, and for an hour or so, you can come live it with me!"

Frankie and 21-year-old Ariana have the same mother, Joan, and the half-siblings remain incredibly close today. Indeed, the elder Grande is currently accompanying his sister on her massive world tour, Honeymoon.

However, while she continues to perform around Europe for the summer, he'll shortly be departing for the US: his own shows kick-off on June 27 in Los Angeles and are scheduled to run for two-and-a-half weeks.
