'The New Us': Will Mackenzie And Josh's Fresh Start Last On Teen Mom OG?

Mackenzie went from declaring, "I hate that I wedded him" and filing for divorce from Josh to once again being engaged to her longtime sweetheart.


Throughout tonight's Teen Mom OG episode, Josh -- who confessed that he was "inappropriate with things" while out of town at a bar -- surprised his longtime love with a bunch of special birthday surprises in the form of a scavenger hunt.


At the end of the "journey" -- which included notes as well as cupcakes, a bible, lunch plus a massage -- was a message telling Mack to throw her first ring "as far as you could in the water." The catch: This was at the location of where he recommended a few many years ago.


although Mackenzie's producer Kristen instructed her not to do it "if it's a real diamond," the mother of three did as beau told her to do because she was beginning fresh."


from then on, she followed rose petals to Josh, who was standing with a sole red rose.


"I love you," he sweetly instructed her as they embraced.


He then got on bended knee with a brand-new ring and stated, "I want this to be the new us. Begin fresh, begin new. Will you marry me?"


Mack accepted with a sweet "mhhmmm," and so they shared a heartwarming embrace.


Nevertheless will the duo's union last -- and will they make it down the aisle a second time? Tell us your thoughts, then catch another Teen Mom OG Tuesday at 8/7c.
