Kenzie Ziegler is the ultimate It Girl. Ziegler, 21, slipped into an itty-bitty bikini while working on her tan on Wednesday, April 22. The Dance Moms alum rocked a black two-piece in a new photo shared via Instagram documenting her spring adventures. She teamed the triangle cup top featuring thick halter straps with tiny string bottoms as she relaxed on a lounge chair in the sun. The singer turned her head and gave the camera a soft smile while accessorizing with black shades. Ziegler went makeup-free while soaking up the rays, and wore her copper hair down and pushed back.
