Ariana Grande’s brother Frankie Grande, 39, was brutally attacked by a 13-year-old in New York

Ariana Grande’s big brother, Frankie Grande, was brutally assaulted by a 13-year-old punk and another teenager in midtown Manhattan, police said Tuesday.

Frankie, a social media personality and the 39-year-old brother of the popular pop singer, was walking on Eighth Avenue between 43rd and 44th Streets around 6 p.m. on November 9 when he was attacked in front of the Satin Dolls Gentlemen’s Club and sports bar, police said.

His robbers, a 13-year-old boy and a 17-year-old man, punched Frankie in the back of the head, police officers said.

Police said Grande was then robbed of his Vuitton bag, which contained his iPhone, AirPods, a pair of sunglasses and his wallet.

He refused medical attention at the scene.

“Thank you all for your thoughts and prayers,” Frankie wrote on Instagram on Tuesday. “I am so thankful to be safe and healed. Stay bright and stay safe out there.”

His attackers were caught shortly after the robbery attempting to use the famous sibling’s credit card at a nearby smokehouse, authorities said.

The teenagers had a fake pistol and a razor blade with them when they were arrested, police said.

The attackers were later charged with robbery, grand larceny, unlawful use of a credit card, criminal possession of a weapon, criminal possession of stolen property, threats and harassment, police officers said.

Their names have not been released due to their age.

According to a local trader, the block, which includes laundry shop Playpen, has been “scary at times” lately with unsavory characters and “lots of kids dealing drugs.

“Any shopkeeper there will tell you they have problems with the drug dealers,” the shopkeeper said. “It has gotten much worse in recent years.

“Everyone knows it’s the place for drug dealers, but cops hardly patrol there anymore.”

Frankie Grande, who wed fiancé Hale Leon in a “Star Wars” wedding in May, raised eyebrows in 2018 when he announced he was in a relationship with husband and wife duo Daniel Sinasohn and Mike Pophis.
