Scherzinger has already shared several posts of her holiday trip in the Pacific, including photos of a Christmas morning sunrise hike in O'ahu and an ugly sweater party with her family.

In the snaps, the two siblings stunned in bikinis while sitting on top of a fence between the pool and ocean.
"Christmas fun in the sun w/ my sis, [Keala Leemon]," Scherzinger captioned her post.

"Sisters forever," a fan chimed in, along with a heart eyes emoji. "Seeing you two together makes me happy. My sisters are my best friends and no matter how many arguments we'd have, we have each other's backs and love each other forever."
