The couple first became official on social media back in November 2019.

"I think I might ride this wave for a while 🏄🏽🌊❤️," Lee captioned a picture of him and Savannah at the beach.

Last year, Savannah shared a heartfelt tribute on Instagram in honor of her boyfriend's birthday, writing, "I am so blessed to have found someone so perfect for me."

"I look forward to being apart [sic] of your growth, and I will always be right by your side through thick and thin. you give me happiness I never knew existed," she wrote at the time. "You have my heart forever and always. ❤️🎁🎉"

Brandon, 44, shares daughter Savannah and son Seth with ex Melissa Ashworth. He is also dad to daughter River Rose, 7, and son Remington Alexander, 5, with estranged wife Kelly Clarkson.

Clarkson, 39, filed for divorce from Brandon in June 2020. She was granted custody of her two children last November, a ruling that she was "pleased" with at the time, according to a source.

In early August — days after a Los Angeles County judge ordered the songstress to pay Brandon nearly $200,000 a month in spousal and child support — a source told PEOPLE that Clarkson is "facing forward" and prioritizing the children.

"Kelly is more than fine. She is doing great and facing forward," a source explained. "She's enjoying the fact that she has the kids for the vast majority of the time and is enjoying time spent with them."
