Ariana Grande’s brother Frankie Grande jumped, robbed of Louis Vuitton bag by NYC muggers

Performer Frankie Grande, the older brother of pop superstar Ariana Grande, was jumped and robbed of his Louis Vuitton bag by a pair of teen muggers in Midtown, police said Tuesday.

The suspects were quickly apprehended — one of them just 13 years old.

The 39-year-old dancer and “Big Brother” star was walking along Eighth Ave. when the two teens crept up from behind near W. 43rd St. and hit him in the head about 6 p.m. last Wednesday, police said.

The duo then struggled with Grande, taking his Louis Vuitton bag, wallet, iPhone and earbuds.

When cops arrived, Grande, who is currently starring in the Off-Broadway musical parody “Titanique,” said he was not seriously hurt and declined medical attention.

Cops grabbed the two teens a short time later when they used one of Grande’s credit cards at a nearby store, and arrested them for robbery.

Their names were not released by the NYPD because they are juveniles.

It’s not immediately clear if the muggers knew whom they were attacking, cops said.

Grande thanked his 2.1 million followers on Instagram for their well-wishes.

“I’m so thankful to be safe and healing,” the LGBTQ celebrity wrote. “Keep shining bright and stay safe out there.”
