It's officially a full house for Lady Antebellum. 

Charles Kelley and wife Cassie McConnell Kelley are expecting their first child. The mama-to-be announced the exciting baby news on her blog, Womanista, sharing an adorable photo of she and her hubby holding mugs which read "mother" and "father." 

"Charles and I are SO BEYOND EXCITED to share with y'all that we are expecting a baby! He or she is due in February and we are so happy we can hardly stand it. Like, ecstatic and I'm crying even as I type those words!" the soon-to-be mother adorably began in her blog post

"This journey to become a family of 3 has been a long, interesting, sometimes fun and sometimes heartbreaking road – a journey that I want to share here at Womanista because I know there are a lot of women out there who have walked the road of a fertility struggle and we can all grow, heal, and understand each other better through our shared experience," she continued.

The blond stunner went on to share that she and Charles "went through several years of trying before finally seeing our fertility doctor in Nashville this past November" at which point they learned they "had about a 1% chance of conceiving a child naturally." 

"We never stopped hoping though. And I want to give a special shout out to my husband, Charles, for being the most incredible human," she wrote. "His love, support, passion for our marriage and our future children has never, EVER waivered, even when the frustration seemed insurmountable. I am so lucky to have a best friend and partner in life like him, and our child couldn't have scored a better dad!"

After receiving the fertility news, Cassie wrote that she and Charles "decided to hang out this summer, relax, enjoy and live our lives fully & happily" 

"We made a plan to regroup this fall and explore other options to expand our family," she shared. "Then it happened. I woke up one morning in June and there it was, a positive pregnancy test. I was in shock. Happy shock, but shock. Our baby decided to join our family in God's time, which is always right."

She continued, noting that she's sharing their story "not to recycle those annoying clichés" but "because it's a happy & hopeful one." 

"My prayer is that if you are struggling with trying to conceive a child, you will remain hopeful," she wrote. "I pray that you will trust God to make a way where there isn't a way. I pray that you and your partner will remain strong and united in your marriage and be thankful for the road that you are traveling and the lessons learned, even when it's really hard.  I pray that your heart remains soft. I pray that your burden is never heavier than the laughter you share with friends. I pray that you will become a mom." 

Cassie concluded by expressing her gratitude for her husband as well as the time they've had as a twosome to build a strong bond. 

"I think back over the past six years of our marriage and am grateful for the time that Charles and I have had together, just the two of us," she said. "I'm grateful for the adventures that we've been on, the places we've visited, the lazy days we've lounged away on the couch together, the late nights spent on the bus talking about our dreams over a bottle (or two!) of wine. I know all of that will change once our little screaming bundle arrives, but our bond that was built during those precious moments will not. God knows us and he knows our marriage and he blessed us in just the right time. #Grateful." 

The news is also exciting for the country music group as both Kelley's bandmates Hillary Scott and Dave Haywood have children

"If he [Kelley] has a little boy, though, we can complete the Lady A...the Baby Antebellum triad," Haywood, who is a dad to son Cash, 11 months, told E! News back in October. Hillary, who is a mom to daughter Elise, 2, added, "Get something in writing, too, 'cause I have a daughter and Cash is a little boy, and if they have a little boy [nods over at Kelley], it'll be like a little Baby A."

Congrats to the happy couple!
