Hitting it out of the park! JoAnna Garcia Swisher and her husband, baseball player Nick Swisher, just welcomed their second child, a daughter named Sailor Stevie.

The Astronaut Wives Club alum, 36, took to Instagram to share the happy news with a snap of her new little girl. "So excited to introduce you to our tiniest princess, Sailor Stevie," Garcia Swisher wrote. "She has stolen our hearts and our family feels complete ❤️, Nick, Jo, & Big Sister Emme #SSS"

The proud parents previously announced that they were expecting their second child via the actress' Instagram this past February. Garcia shared a trio of snaps — one of which featured their first daughter, Emerson, standing in a crib with an "eviction notice" sign — with the news.

"Nick, Emme and I are so excited to finally share this news," she captioned the post, adding baby and milk bottle emojis.

The happy couple have been married since 2010, when they tied the knot in front of famous friends (including Lance Bass, Cameron Diaz and Reba McEntire) in Palm Beach. They later welcomed Emerson, nicknamed "Emme," on May 21, 2013.

As little Emme grows up, Garcia Swisher said she only has one piece of relationship advice to offer. "I'd say, 'Don't be afraid to make mistakes and always respect yourself,'" she told Glamour last year. "I say this to a lot of my friends, but what's the worst that can happen? If you want to be all in and fall head over heels in a matter of minutes, then go for it. Obviously be safe and be protective of your body and your heart, but I feel like nobody can disrespect you unless you really allow them to."
