Robertson, 19, first broke the news during her interview with FOX411. "Me and Trevor actually just broke up," she said. "It's OK, it's fine."

"I can say even after we broke up, he's a great guy and I think he's doing amazing things in his career," she continued.

Prior to their split, the duo were not shy about sharing pics of each other over social media. Just last week, Knight posted an adorable 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, writing, "Wake up & count your blessings this morning."

Amid their breakup, the two will have no problem keeping busy. College football is officially back in full swing, with Knight playing in his first Aggies game of the season against the UCLA Bruins on Saturday. Meanwhile, Robertson is gearing up for her Live Original Tour, which kicks off Sept. 22 in Allen, Texas.

ET caught up with Robertson back in August, where she couldn't stop gushing over the 22-year-old athlete, whom she had just started dating at the time.

"We've been dating for three weeks, so it's super chill," she said. "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."

Their romance sparked when the two attended a Justin Bieber concert together in Texas, where Knight lives.

"He was messaging me, and I was like, 'Uh, do you want to go to a Justin Bieber concert with me? Because I don't have anybody to go with,'" she told ET. "And he was like, 'Sure.' So, he came and I guess we just hit it off."
