After about a month of dating, public speaker and Duck Dynasty's Sadie Robertson and her 22-year-old Texas A&M Aggies' quarterback boyfriend, Trevor Knight, have stopped seeing each other. Robertson released a statement:  "Trevor Knight and I are no longer an item. It was just too hard to spend time together."

"Trevor is a great guy, but our schedules are just so busy right now," Robertson, 19, told Us Weekly in a statement. "He's in the middle of football season, and I'm about to start my tour, so the timing just didn't work."

Robertson opened up about the breakup to Fox411 on Thursday:  "Me and Trevor actually just broke up. It's OK, it's fine," she said. "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 Dancing With the Stars alum began dating the Texas A&M quarterback in July.

"We've been dating for three weeks, so it's super chill," she told Entertainment Tonight on August 8. "He had messaged me because he goes to Haiti every year on a mission trip and he saw that I go to Haiti. We just kinda' connected through that, very much friends at first." The two later went to a Justin Bieber concert for their first date.

Robertson is preparing for her live tour, which starts Sept. 22 in Texas, "We've been working on this [tour] for the last year...I'm very excited about everything coming together," she said.

Prior to their split, the duo were not shy about sharing pictures of each other over social media. Just last week, reports ET, Knight posted a black-and-white selfie to his Instagram, captioning it, "Just because I miss ya."

"Over 300 miles away & she still managed to surprise me with delicious brownies," he tweeted on Saturday. "@sadierob knows the way to my [heart]!"

Robertson echoed Knight's sweet sentiments one week earlier, posting a photo of the two of them and writing, "Wake up & count your blessings this morning."
