At the reunion, the star also showed off her fit physique in a glamourous sequin-covered bronze spaghetti strap gown. Southern Charm New Orleans star Reagan Charleston told Dennis how much she loves the new look in the comments of Shea's Instagram post. "@kathryndennis you look amazing!!!!!!" Charleston said. Fans agreed too. "HOLY CRAP @kathryndennis !!! WHAT A GLOW UP!!!" said one fan. Someone else commented, "Whoever does her hair should get a raise :-) beautiful." Before dyeing her hair, Dennis snapped one final selfie with her auburn hair where she snuggled up alongside 6-year-old daughter Kensie Calhoun Ravenel. "Me and my mini feelin a lil @fendi ;)," she captioned the photo of the mother-daughter duo wearing matching Fendi outfits. Dennis, who shares daughter Kensie and son Saint, 4, with ex Thomas Ravenel, took the next step with her boyfriend Chleb Ravenell this fall by making their relationship Instagram official. (Despite their very similar last names, Dennis' ex Ravenel has no relation to her current boyfriend Ravenell.) "They've been dating a few months now," a source told PEOPLE of the couple back in July. "They have good chemistry together. "He's met the kids and is good with them."
