On Sunday, friends and family, including Honey Boo Boo (Alana Thompson, 7) and big sisters Pumpkin, Chickadee and Chubbs, joined the duo in their Georgia backyard for a ceremony to celebrate their love, followed by a rowdy family barbecue on what happens to be Cinco de Mayo.
"The day was very special mostly because my girls were able to take part in it," says June. "I felt like it was important for them to see this moment and celebrate my love for Sugar Bear."
The fun-loving family, whose series returns to TLC July 17, didn't go over the top with the celebration.
"My sister baked the cake, and we spent most of the money on barbecue," says June. "We stayed true to our roots and made the focus on the family and my commitment to Sugar Bear. You can definitely plan an event on a budget!"
And whether or not they're actually married, June says she's found the secret to keeping her relationship strong.
"Never settle for a man who doesn't treat you right," she says. "If a guy doesn't love everything about you, move on! There are plenty of other fish in the sea."
"I give this advice to my daughters," she adds, "because I always want them to be themselves and surround themselves with people who love them for them."
