"Duck Dynasty" star Sadie Robertson has been spending a lot of time with Texas A&M quarterback Trevor Knight, and they have let people get a glimpse of their relationship through their photos in social media.

It was Knight who started the rumour mill on their relationship when he shared a snapshot of his date with Robertson during a Justin Bieber concert on his Instagram account (@trevor_knight9). Robertson then followed by posting a photo of their tennis match on her Instagram account (@legitsadierob).

"Tennis - 1 dimple duo - 0," she captions it. The photo shows Knight's hand resting on Robertson's waist, while the teenager has her foot up as one of her arms is wrapped around Knight.

This time around, Robertson all but confirmed their relationship when she posted another photo of her and Knight during Reed Robertson and Brighton Thompson's engagement party.

The photo shows the teenager, who was wearing a gorgeous off-shoulder floral maxi dress, with her arms wrapped around Knight, who was wearing a casual plaid shirt and shorts. "'Hip hop R & B'... good one Trev. So happy to celebrate@officialreedrob & @bright1thompson tonight!" she captions the photo.

Robertson split from long-time boyfriend Blake Coward earlier this April. She opened up about their break-up on her YouTube channel, although she did not reveal the reason behind their split.

"About a month ago Blake and I broke up, which was a shock to a lot of [you]," she says in the video. "It was not how we would wish things would end, but it's what happened. We feel like this is the best thing."

She adds that she did not want to be "bound in bitterness" that things did not work out between her and Coward. She says she hopes that good things will happen to Coward even though they have gone their separate ways.

"This is what I hope for Blake. I hope that Blake finds somebody so much better than me in every single way. Because if I wasn't right for him, I know somebody is perfect for him. Because I do love him. I did love him a lot," she says.
