The on-and-off again couple allegedly got into a heated argument while at the Las Vegas strip club Hustler, a source told PEOPLE. “She was mad about something she saw on his phone [and] she freaked out.”

The source claimed Harley then allegedly “lunged” at the Jersey Shore star as he tried to leave the club.

She was restrained by his friend, but when he was walking out she “took an ashtray from the table and threw it at his head, busting his nose and lip,” the source continued.

On Friday, while Harley did not address the arrest, she posted photos of her and Ariana Sky from last weekend.

“Mother’s Day 2019,” she captioned the photo, along with a flower emoji.
