Kelsea Ballerini has a must-see bikini body. Ballerini, 32, took to Instagram on Thursday, December 4, to show off moments from her trip to Australia. In her photo dump, she stunned in a cherry red bikini featuring halter straps that tied in a bow behind her neck. Ballerini teamed the triangle top with high-cut bottoms. She layered a white tiered flowy skirt over her swimsuit while catching some rays. She styled the number with brown shades and gold hoop earrings. Her blonde hair was pulled back and styled in a messy - but chic - bun.
