Carrie Underwood has created a new swimwear line, and she announced the venture by posting a picture of herself in a bikini to social media on Friday (April 1).

Underwood is well-known for her commitment to staying fit and toned, even maintaining most of her exercise regimen while she was pregnant with her son Isaiah last year. She released a line of sportswear called Calia by Carrie in 2015, and according to her post, her new swimwear line is an extension of that collection.

"I'm so proud to be able to work with Dick's Sporting Goods to create a line of swimwear that makes me feel so good! Adorable and athletic...and covers everything I want covered!" the "Heartbeat" singer posted to Facebook, with the tags CALIA by Carrie, ‪#‎staythepath,‬ ‪#‎summeriscoming and‬ ‪#‎vegas‬.

Like all of Underwood's Calia by Carrie line, the swimwear is available exclusively at Dick's Sporting Goods. Take a look at some of the pieces by visiting the retailer's official website, which already features a wide range of items.

Underwood doesn't just lend her name to the line, she stands behind it, too. In fact, the superstar singer had a little fun with shoppers at a Dick's location in Nashville in February when she went undercover as a Calia rep, hiding behind a wig and dark glasses to wait on some of the actual customers who were browsing the line. She ended up leading a singalong over the store's loudspeaker after several shoppers finally recognized her.
