YouTube stars Sophia Grace Brownlee and Rosie McClelland may have an affinity for the spotlight (and tiaras), but a week ago, the duo allowed Rosie's mom, Danielle, to be princess for a day!

The 12-year-old and nine-year-old cousins served as bridesmaids in the wedding of Rosie's parents, taking to Instagram to share photos from the nuptials.

"My mummy & daddy got married! I loved being a bridesmaid," Rosie wrote next to a photo of her mom in a wedding dress, while Sophia Grace captioned a pic of herself, "Amazing weekend with all my family for my Aunty Danielle's wedding."

The duo first rose to fame thanks to their cover of Nicki Minaj's "Super Bass," getting the attention of Ellen DeGeneres. After appearing on the comedienne's talk show multiple times, the pair became mini-celebrities, and Sophia Grace is currently working on songs for an EP.
