Duck Dynasty star Sadie Robertson is a single girl again.

Robertson, who also competed on Season 19 of Dancing with the Stars, has revealed her relationship with boyfriend Trevor Knight has ended, Us Weekly reported.

"Me and Trevor actually just broke up. It's okay, it's fine," Robertson told Fox411 on Thursday.

Robertson, 19, and Knight, 22, split after dating for a little more than one month.

As recently as August 25, Knight posted an adorable black-and-white Instagram photo of the couple, writing, "Just because I miss ya."

"Trevor is a great guy, but our schedules are just so busy right now," the reality TV star and motivational speaker told Us Weekly. "He's in the middle of football season, and I'm about to start my tour, so the timing just didn't work."

Knight is the quarterback for Texas A&M, while Robertson will be speaking around the country for her Live Original Tour starting September 22.

The pair sparked a romance in July when Knight messaged her about something they had in common -- volunteering in Haiti. After maintaining a friendship, Robertson and Knight eventually went on their first date to a Justin Bieber concert.

Prior to getting involved with Knight, Robertson dated Blake Coward from her hometown. They were together for two years but told Us in March they had decided to call it quits.

Robertson danced with pro Mark Ballas on Dancing with the Stars back in 2014 and finished in second place behind winner Alfonso Ribeiro and his pro partner Witney Carson.

Duck Dynasty is currently airing its tenth season on A&E. Dancing with the Stars is set to return with an all-new season Monday, September 12 at 8PM ET/PT on ABC.
