Luke Bryan and his wife Caroline bid an emotional farewell to their nephew Til Cheshire as he left for college.

Caroline shared a post on Instagram over the weekend revealing she dropped off their 18-year-old nephew at a college in the couple's native state of Georgia.

She announced the news with a photo that shows her giving her nephew a heartfelt embrace, alongside the caption, "I left a big piece of my heart today in Georgia. Been dreading this day for years, but I guess it’s time for Til to fly. Still can’t handle it right now! Good luck in college my sweet boy."

The country superstar wrote in the comment section, "I keep looking to see if his truck is parked next to mine," accompanied by a crying face emoji.

The couple adopted Til and his sisters Jordan and Kris after the death of the singer's brother-in-law Ben Lee Cheshire in 2014. Ben was married to Luke's sister Kelly, who died suddenly in 2007.

Luke and Caroline also share two sons, Bo and Tate.
