Prepare to see Honey Boo Boo as a flower girl! Her older sister Anna “Chickadee” Shannon is getting hitched!

As we loyal fans know, the 19-year-old and her truck mechanic boyfriend, 21-year-old Michael Caldwell, publically announced their engagement during the Season 3 finale. Now we know when the wedding will be taking place: in just a few weeks!

Chickadee and Michael will say “I do” on May 3 in a backyard ceremony at a friend’s home in Georgia, a source tells RadarOnline.com. “They planned the entire wedding themselves, with no help from a wedding planner,” the source adds. “Anna and Michael are even writing their own vows!”

Sounds like this wedding will have the kind of homespun charm that’s made us come to love the whole Honey Boo Boo family. But in case you’re worried the couple’s staying casual for the big day, never fear. The laidback Chickadee will wear a white silk gown with sweetheart neckline and a long train, while her bridesmaids — sisters Jessica and Pumpkin, and best friend Candace — will wear white and teal dresses purchased from Forever 21.

Chickadee’s 19-month-old daughter Kaitlyn will serve as a flower girl alongside her aunt Alana, with the ceremony followed by an old-fashioned Southern cookout. And yes, the whole thing will be filmed for an upcoming season of the TLC mainstay so start planning your watch party now.
