Rebecca exchanged vows with fiance John Reed Loflin at an intimate ceremony in Mexico on Saturday, and the glowing bride looked gorgeous in a Sherri Hill gown, complemented with a sheer, flowing white cape.
Rebecca's sister, former "DWTS" runner-up Sadie Robertson, snapped a photo alongside family members (and fellow bridesmaids) Mary Kate and Bella Robertson, which she shared to Instagram during the big day.
"WOW WOW WOW what a wedding," Sadie captioned the cute pic. "Every single moment was just absolutely priceless. I will cherish the memories forever! I love seeing my family grow."
One day before exchanging their vows, Rebecca shared a sweet photo of her kissing her betrothed after their rehearsal dinner, which she captioned, "Surrounded by people we love. tonight was truly magical."
After the ceremony, Rebecca shared an animated Instagram pic, showing her celebrating with her bridesmaids.
Rebecca -- who was born in Taiwan -- joined the Robertson family in 2004 as a foster child after coming to the United States as a foreign exchange student at age 16. She and her new husband met at the 2014 Voodoo Fest in New Orleans, and announced their engagement back in January.
