Carrie Underwood Stuns In Skimpy Bikini Sunbathe On The Beach

Carrie Underwood tends not to share too many swimwear moments to her social media, but when one lands on her Instagram, fans go wild. The country singer, 39, sizzled in a strapless bikini as she topped up her tan on the beach this May, posting with girlfriends and solidly entering chill mode.

Showing off her jaw-dropping workout body in a colorful, skimpy bikini, Carrie wowed her army of fans as she peeped her famous abs, although her followers did have to swipe for the snap. Enjoying a vacation with her sisters-in-law, Carrie dedicated her post to "sisters" who might not be ones by blood, but the family vibes were all there. Fans have left the "Before He Cheats" hitmaker over 220,000 likes.

Scroll for the photos. The gallery opened with a balcony-set shot of Carrie posing backed by ocean waters and modeling a cute, floral-print maxi dress. Smiling with three other ladies, the American Idol winner returned in a swipe right for a fun selfie, once again joined by her travel companions.

Upping the ante with her gym-honed body in a further image, Carrie stunned as she soaked up the sun under beating rays, here showcasing her curves and her muscles in a strapless, seashell-esque bikini top in hot pink, green, yellow, and turquoise, again opting for leafy floral prints. The blonde was back in selfie mode as her gal pals joined her for a beach sunbathing, with everyone lying in a row.

Carrie had paired her multicolor bikini top with hot pink, stringy bottoms. Flashing her world-famous legs as she lay on a deckchair, Carrie smiled for the camera while rocking tinted shades.

Further images included more beach and indoor moments, plus the tattoos that Carrie and her sisters-in-law all got during their trip. In a caption, the singer told fans: "Sisters…not by blood…but sisters nonetheless. God truly showed us great favor by putting us all together... It’s true that you don’t get to choose your family, but if I could, I would choose these three women to be my sisters-in-law!"

Detailing more about the new ink she'd gotten, Underwood continued:

"From the beach to the tattoo parlor, Destin didn’t know what hit it! I love you ladies!!"

Carrie has since shown off her super-fit figure in sporty looks from her CALIA line while promoting her Fit52 workout app. Showing off her killer legs in flimsy gym shorts and a pale pink tank top last month, Carrie posed confidently from a yoga mat as she also flaunted her shredded arms and sculpted shoulders.

Marking Black Friday as she tempted newcomers with a sweet discount, Carrie told fans: "Get 50% off the annual price (that’s $39.99 US for the year!) when you sign up between now and November 27."
