Christie took to Instagram to share the big news of her return to SI -- marking her ninth time as a model in the prestigious Swimsuit Issue -- " I am excited to announce that I am back in @si_swimsuit ..I figured with my gorgeous daughters @alexarayjoel and @sailorbrinkleycook by my side whose going to be looking at me!"
She also addressed the subtle detail that she appears to be floating above the surface of the idyllic tropic water, joking, "My kids think I walk on water, so let's not mention the apple box concealed just under the surface."
Christie concluded by thanking Sports Illustrated for "sending a powerful message that good things come in packages of every size and we do not come with an expiration date!"
The icon and her gorgeous daughters also posed for some striking solo photos. Alexa Ray rocked a black bikini complete with some floral embellishments while Sailor went for a tropical-inspired print for her tiny two-piece, and Christie opted for a fire-red bikini that complimented her flowing blond locks.
