Hungry beach babe! LeAnn Rimes got a case of the munchies while sunbathing on the beach in Hawaii Thursday, Feb. 6. The 31-year-old singer was spotted eating a sandwich while wearing a skimpy bikini.

Rimes rolled onto her stomach to chow down on her lunch while sunning herself on a reclined beach chair. While enjoying her meal, the "Swingin'" singer showed some skin in a Tori Praver Kalani bikini top in Rust, and coordinating Boardwalk Bottom in Supurba Rust. The stylish swimwear top and bottoms retail for $209 combined.

She was later photographed wearing a second colorful halter-top bikini, which similarly showcased her slim and toned body. Rimes has been on a romantic Hawaiian vacation with husband Eddie Cibrian for the past week. In addition to flaunting her abs in numerous two-piece swimsuits, she's been playing tourist during her travels.

The country-pop singer has shared photos on Twitter of her marine-life encounters, too: shark diving and whale watching. In one close-up shot of a shark, Rimes wrote, "Say hello to my little friend."
