Robert F. Kennedy Jr.’s daughter Kyra Kennedy, 20, used Instagram to pick on a New York magazine blogger — and now she’s being forced off social media by her dad, his reps told Page Six.

The bullying brouhaha began when Allie Jones of New York magazine fashion blog the Cut wrote a short post about a New York Times piece on Kennedy and her pals Andrew Warren and Gaïa Matisse called “Move Over, Rat Pack and Brat Pack: Here Comes the Snap Pack.”

Taking offense, Kennedy commented on Jones’ Instagram feed: “I can play games too bitch,” and “clearly taking your insecurities out on others. We can play too.” Jones then posted another piece, “I’m Being Cyberbullied on Instagram by a Kennedy.

Kyra deleted her comments. But a rep for her dad, RFK Jr., told us, “Mr. Kennedy has spoken to Kyra and informed his daughter that their family does not bully people. He has instructed her to shut down all of her social media accounts immediately.”

Page Six reported last year that when Kyra was refused entry at an upstate New York nightclub, she screamed at security, “I am a Kennedy, Google me!”

Meanwhile, Warren writes online that Jones is “an unprofessional writer who has nothing better to do [and] keeps trying to make you look bad but really she’s the cyber bully who started and won’t give up.”
