How did Addison and Jeremy meet?

Before they became #RelationshipGoals, Jeremy and Addison were first co-stars and then friends. In fact, the mother-to-be has shared several #tbt photos of the couple from their younger days, including a snapshot of the pair on the set of Afterschool in 2008. They were both 17 years old at the time.

Addison’s first ~romantic~ post with Jeremy dates back to 2016. Prior to that, Jeremy was always in the background, but never seemingly her boyfriend. Most of her captions referred to him as her “best friend.” We bet she’s happy she took him out of the friendzone now!

Are Addison and Jeremy getting married?

Though they seem ridiculously happy and in love, neither Jeremy nor Addison has ever gone on record to discuss the potential of nuptials. TBH, we’re totally cool with that. It’s 2018, after all, they don’t need to be married to have a baby! This isn’t a royal family situation we're talking about.
