The proud mum-of-three announced the exciting news on Instagram.
"Thrilled to be the @barbie Christmas ambassador for 2016! So many great new Barbie toys for the festive season," the 33-year-old penned alongside a stunning image of herself in a Barbie-inspired lilac dress.
Hubby Lleyton Hewitt was quick to congratulate his wife of 11-years.
"Gee the missus looks," he captioned the same image, adding in a fire emoji, along with "#BarbieAmbassador #ProudHusband."
Chatting to The Daily Telegraph about the doll endorsement, the actress/singer mused, "I think it's nice in today's world for kids to get away from all the technology and use their imagination."
This exciting new gig comes after mum to Mia, 10, Cruz, eight, and Ava, six, hinted at a return to the spotlight.
At Derby Day, the former Home and Away actress said, “I am happy to get back out there and work again.”
“This year was all about settling the kids in at school and hopefully there are some opportunities in 2017. Being here with Lavazza, I am just so happy to be out, I feel like a grown up.”
