Emily Robertson of Carter's Chord is pregnant! The singer announced this week that she and hubby Marc "Butter" Fortney of Trailer Choir are expecting their first child -- a boy -- in October.

"We would like to announce……..that this October…..we are expecting A BABY BOY!!!!!" the enthusiastic couple revealed on Carter's Chord's official blog. "We have waited to share the good news with all our fans and it feels so good to be able to tell the world! We feel incredibly blessed to be embarking on this new part of our lives and can’t wait to be parents to our little boy. God is oh so good."

The parents-to-be have been married since September 2010 after a rather unorthodox wedding. Family and friends arrived at Nashville's famed 12th and Porter venue in what they thought to be Butter's birthday party, but after Robinson accepted Fortney's marriage proposal onstage, a curtain dropped to reveal flowers and an altar.

Speaking about the surprise ceremony, Fortney says, "Emily and I wanted our wedding to reflect what was important to us, and how much we love each other" (quote via Country Music Is Love). He further explains, "Expensive invitations and fancy ceremonies don't matter to us – I mean the altar cost us $30 bucks worth of PVC pipes Plus we both have this wacky sense of humor, and being able to pull off a surprise like that was great."

Fans excited to give the couple well wishes in person don't have to wait long. Both Carter's Chord and Trailer Choir are scheduled to appear during Nashville's annual CMA Music Festival in June. Says the couple, "Hope to see all of you at CMA Music Fest next week. You can’t miss the baby bump!!"

Emily Robertson's sister and fellow songstress Becky tied the knot earlier this year, so we wouldn't be surprised if more Carter's Chord babies were on the horizon. The group is best known for their songs 'Love a Little Bigger' and 'A Little Less Comfortable.'
