'Jersey Shore' Star Ronnie Ortiz-Magro & Jen Harley Not Rekindling Romance, Yet

EXCLUSIVE

Ronnie Ortiz-Magro's hanging with his baby mama a little more than a week after she allegedly dragged him with her car ... but it's not all amoré just yet.

Sources close to the on-again-off-again couple tell TMZ the 'Jersey Shore' star and Jen Harley were spending time together this week, including on the 4th of July. We're told Jen flew out to Jersey earlier this week, and the pair's been kickin' it for a few days now.

All that said ... our sources say Ronnie and Jen are not officially back together at this point. They're simply working things out for the sake of their daughter, Ariana.

We broke the story ... Jen dodged domestic violence charges after getting busted at the end of last month for allegedly bloodying Ronnie up during a fight in the car.

The incident left one hell of a bloody mess behind, inside the car and out.

Despite Ronnie's close friends wanting him to stay away from her out of fear for his safety, he seems to be doing things his way. So far, so good -- we're told he and Jen have had no major issues this week.

Ronnie still wants a formal child custody agreement though -- he wants a 50/50 split.
