Despite breaking up with her high school boyfriend Slade Osborne in 2015, Brielle Biermann decided to give the relationship a second chance following her split from Mike Kopech in 2018. As teenagers in love, Biermann and Osborne once talked about marriage, kids, and moving to Los Angeles together. Sadly, the young couple split, and Biermann later revealed in a statement to E! News that Osborne wasn't the man she thought he was.  

When the couple re-kindled their romance in 2018 all appeared well; Biermann even expressed her love for Osborne in an Instagram post. In the post she wrote, "SCREAMING HAPPY BIRTHDAY to my best friend, my angel, my love forever! You've been one of the best things that's ever happened to me for the past 5 years and I couldn't imagine a life without your silly self!"

Unfortunately, a second time was not the charm for the couple. Biermann confirmed her break-up from Osborne in an interview with Page Six on February 20, 2019, stating, "Um, I'm single. So, there's that. ...We definitely tried it out [again]... and you'll see how that plays out on 'Don't Be Tardy'..."
