"Duck Dynasty" star Sadie Robertson has split from Texas A&M quarterback Trevor Knight, the reality star told FOX411 exclusively.
"Me and Trevor actually just broke up," Robertson told FOX411. "It's okay, it's fine."
She added, "I can say even after we broke up, he's a great guy and I think he's doing amazing things in his career."
The 19-year-old first announced she was dating Knight in August after meeting the football player in May.
"We've been dating for three weeks, so it's super chill," the "Dancing With the Stars" runner-up star told ET on August 8.
Robertson previously dated Blake Coward for two years before calling it quits in March.
But the reality star won't have too much time to dwell on her breakup -- she kicks off her "Live Original Tour" September 22.
"We've been working on this [tour] for the last year...I'm very excited about everything coming together."
