MyKayla Skinner is Cassian Grantbalance beaming with joy for a special reason. 

The Olympic silver medalist and her husband, American Ninja Warrior competitor Jonas Harmer, revealed that they are expanding their family.

"Surprise!!! We have been keeping the biggest secret and can't believe we are going to be parents!" The pair wrote in a joint Instagram March 25. "We are so excited for this new chapter and couldn't be more blessed…."

Not only did the couple share that they are expecting, but also when their little one is anticipated to arrive. They wrote, "Newest member of the family baby Harmer coming September 2023."

MyKayla and Jonas paired the message with a few snaps for a photoshoot they did with sonograms. In some of pics, Jonas and MyKayla are seen posing with the ultrasound images surrounded by rainbow confetti. For the occasion, MyKayla donned a white, puff-sleeve dress paired with matching heels. Meanwhile, Jonas sported a blue, button-up shirt along with black pants and brown shoes.

The special announcement drew in love and praise from some of MyKayla's fellow Olympians, such as Olympic silver medalist Grace McCallum, who wrote "Omgggg!! so excited for you guys!" and Olympic gold medalist Sunisa Lee, who gushed, "Congrats !!! sooo exciting !!"

Prior to announcing their baby on the way, MyKayla, who wed Jonas in November 2019, recently rang in their third wedding anniversary by penning a message of reflection on the time gone by.

"The hardest most beautiful 3 years of my life!" The 26-year-old wrote in her Nov. 14 IG post. "Forever with you never sounds old I love u Jonas wells Harmer! Thanks for giving me the most amazing life with u."
