Ronnie Ortiz-Magro and Jen Harley are like a broken record, and a trip to Disney World's not going to fix it ... so say sources close to the volatile pair.
We broke the story ... the 'Jersey Shore' star and his baby mama looked more like they were going to prison than vacay early Wednesday morning as they boarded a flight from Las Vegas to Florida with their daughter. They didn't sit together or speak on the flight.
We're told the separate seating was due to booking last minute -- but seeing the moody duo together definitely raised eyebrows.
Our sources tell us looks do not deceive -- Ronnie and Jen are still far from being solid in their relationship and are "on and off" on a weekly basis. We're told family and friends close to them are very concerned and fear things will take another violent turn at any moment.
Yes, even at the "The Most Magical Place on Earth."
