Jersey Shore Fans Suspect Ronnie Ortiz-Magro Got Engaged Over the Weekend

Jenn Harley's arrest came as Jersey Shore fans speculated that her ex Ronnie Ortiz-Magro got engaged with his girlfriend Saffire Matos. 

The speculations surfaced came on Saturday, June 19, as the fans piece together different photos of Matros and Ortiz-Magro together on social media, Screen Rant reported.

The fans also speculated that Matos was pregnant, which is why the engagement between the couple was allegedly rushed.

According to Screen Rant, a Reddit user used impressive detective skills to piece together the speculation that the couple got engaged this weekend.

The woman in the photo was believed to be Matos as the woman wore the same dress Matos was seen wearing on her Instagram Story posted on Saturday, June 19.

Despite the speculations, both Ronnie Ortiz-Magro and Saffire Matos have yet to confirm or deny the engagement rumors.
