What does one wear to celebrate their 42nd birthday? Well, if you're Kim Zolciak Biermann, the answer is quite simple: a cheeky bikini, of course. In honor of her special day, the Don't Be Tardy mama decided to share a steamy swimsuit snap on Instagram, showing just how sexy 42 can look in a swimsuit. Honestly, we wouldn't have expected anything less from the bikini queen.

Posing by her incredible backyard pool, Kim flaunted her smokin' hot bod in a pink string two-piece swimsuit featuring a halter top and tiny, barely-there ruched bottoms. Ever the fashionista, Kim accessorized her swim look with a cute matching pink headband. "Thank you ALL for the birthday wishes! I can’t believe today I’m 42!! Like holy s--t.. that use to be sooo old to me when I was in my 20’s now I know it’s young AF," she captioned the May 19 post.

Kim's sexy bikini is from none other than her upcoming swimsuit brand, Salty K. (You've probably seen her new flirty designs on daughters Brielle and Ariana recently.)

"This last year hasn’t been an easy one and I was so ready to see 2019 go, BUT I’m also incredibly thankful for 2019 as this is the year I decided it was time to chase another dream of mine. SWIMWEAR." Kim wrote. The ATL entrepreneur, who also launched KAB Cosmetics along with Brielle and Ariana in 2019, revealed that her "love of the ocean" and "passion for swimwear" is how her new business venture all started.

Not only are Kim's bikini designs playful and sexy, but they are also eco-friendly. "Fun Fact: I love the ocean so much that I want my children, my grandchildren and future generations to enjoy it as much as we do now so when creating “Salty K” my fabrics were important to me. They are sustainability sourced and ethically produced. Even my tags are made from recycled paper. Can’t wait to see what you think," she shared.

Mark your calendar: Salty K will be available June 1.
