One of the moms on MTV‘s “16 and Pregnant” … is now 17 and legally banned from going anywhere near her baby daddy … TMZ has learned.

19-year-old Josh Smith got a huge victory in a Florida courtroom Tuesday … when a judge granted his request for a restraining order against his baby mama Jennifer Del Rio.

As TMZ previously reported, both teens wanted restraining orders against each other — but Jennifer didn’t show up on the scheduled court date … so Josh won by default and Jen’s request was thrown out.

According to court docs, Jennifer must stay at least 100 feet away from Josh at all times — and she’s also banned from hanging around his car and his house.

As for their twin boys — the documents show Josh and Jen are still temporarily sharing custody until a more permanent agreement can be locked into place.
