MacKenzie Porter has a new collaboration on the way.

The singer, who fans fell in love with on her multi-week chart-topper with Dustin Lynch, “‘Thinkin’ ‘Bout You,” is going to be a mommy.

Porter and her musician husband Jake Etheridge revealed they are expecting their first baby in a joint Instagram post on Thursday. Porter will launch her headlining Canadian tour on Friday.

“Our sweet baby,” the post read. “We couldn’t be more excited to meet you, hold you, kiss your lil squishy cheeks and let Willa lick your lil toes. To say we are a tad nervous would be an understatement but what we know without an ounce of doubt is that we will love you more than anything in this entire world. We will never go back to who we were before. WE are now THREE (well 4 including the fur bean) forever.

Love Mom and Dad”

Willa is the couple’s dog.

Porter’s country counterparts piled congratulatory messages on the singer’s sweet post, which included a host of bare bump pictures and her husband.

“Yassssssssss congrats momma,” Jana Kramer said. Kramer is pregnant with her third child, which is due soon.

Maddie & Tae’s Taylor Kerr added: “CONGRATS!!!! Mama hood is the best. So happy for y’all ❤️”

And Madeline Edwards said: “OMGGGG so exciting! Congrats”

Porter attended CMT’s “Smashing Glass” taping last week where she said she was excited to be invited to such events because a couple of years ago, before her duet with Lynch, she didn’t make the list.

“I’m not only friends with a lot of amazing female artists in this city, but to be able to share a night like this supporting other women and empowering other women, It’s just so cool,” Porter said.

CMT’s “Smashing Glass” honors Patti LaBelle and Tanya Tucker, and is an all-new, genre-defying musical salute to the incomparable women who defiantly blazed trails for future generations of female artists.

"CMT SMASHING GLASS" will premiere Wednesday, November 15th at 9p/8c, exclusively on CMT.
