It's not even bikini season and Grammy winner Carrie Underwood is treating her fans to a sneak peek of her outstanding bikini bod'!

The 33-year-old mom shared a poolside snap on Instagram which displayed her ab-tastic body in a floral bikini on April 1. The colorful floral find isn't just any old bikini, the sports-bra style two-piece is one of the swimsuits that is available from her CALIA fitness apparel line at Dick's Sporting Goods.

Along with the toned image, Carrie wrote, "I'm so proud to be able to work with @dickssportinggoods to create a line of swimwear that makes me feel so good! Adorable and athletic...and covers everything I want covered! @caliabycarrie #staythepath#summeriscoming #vegas."

In the November 2015 issue of Shape magazine, the new mom talked about getting her figure back in shape after the birth of her son, saying, "After I had Isaiah, my goal was to take control of my body again. I was lucky: I gained only 30 pounds, which is the recommended amount, and I exercised throughout my pregnancy."

The country girl went on, "I did have a C-section, which meant waiting six weeks before working out. Within 10 days, though, I was able to begin walking slowly on the treadmill and around my neighborhood. It felt so good to be active!"

Carrie also explained her vegan diet helps her with that taut tum of hers. She said: "I'm vegan and I love bread, but recently, I started making dinner a breadless meal. I'll have a bowl of oatmeal for breakfast, and I'll make a sandwich on Ezekiel bread for lunch, but in the evening I'll have protein and vegetables and no bread. When I wake up, my belly is flat!" It certainly is!

Meanwhile, just a few hours after posting the bikini photo, the former American Idol got all gussied up in her fringed best when she headlined the ACM Women of Country Night event during the 2016 ACM Party for a Cause Festival at the Las Vegas Festival Grounds. For the event, the big-voiced singer opted for a ripped pair of black skinny jeans and a sparkling fringe top.

The other ladies who lent their vocals to the big night included Kelsea Ballerini, Martina McBride, Kellie Pickler, Maddie & Tae, Lauren Alaina, Kelleigh Bannen, Brandy Clark, Miranda Lambert and Jana Kramer.

The event served as a mini "American Idol" reunion since Carrie won season four in 2005, Kellie came in sixth in season five in 2006 and Lauren placed second in season 10 in 2011.

Carrie is next set to perform on April 3 during the 51st ACM Awards at the MGM Grand in Las Vegas, Nevada.
