The three members of Lady Antebellum -- Charles Kelley, Hillary Scott and Dave Haywood -- have come a long way since their debut single, 'Love Don't Live Here' hit the airwaves in 2007. Back then, they were three single 20-something aspiring artists, content to live the carefree life while crossing the country promoting their self-titled debut album.

Fast forward five years, and two of the members, Charles and Hillary, are enjoying marital bliss with their respective spouses, while Dave works on wedding plans with his fiancée, Kelli Cashiola. It's a change Hillary says they are all happy to embrace.

"We've always had a really close friendship from the beginning, but I think we've seen each other grow," the recent bride (to drummer Chris Tyrell) explains to Country Weekly. "I'll speak for myself that I'm in a much happier place. We're excited to all be going through the same things quickly after the other, so it's really fun. Love is in the air."

Charles, who was the first to walk down the aisle in 2009, when he wed publicist Cassie McConnell, says having his bandmates also in committed relationships makes it easier for him.

"They can relate to me now," he says. "I was the first one to get married and it was very interesting coming onto a bus with two single people, so it's nice [that they are] going through the same thing."

Now that they have each found their soul mates, the obvious progression is to add children to the mix. "We're gonna figure out the next step when kids come, what that's going to be. We'll stick them in the bottom bay of the bus so you don't hear them when they cry," Charles jokes.

"[We'll] make a really wicked nursery under there," Hillary adds. "The family's grown."

For now, the trio are enjoying their current status as a multi-platinum-selling act, nominated for Best Country Album at the Grammys as well as four just-announced ACM Awards, including Top Vocal Group.

"I think you have to enjoy where you are in that moment," maintains Hillary. "I have a lot of great memories being single on the road with these guys, but I'm also so excited about starting a life with my husband and the fact that it's a new chapter."

Lady A will kick off the 2012 leg of their Own the Night tour tonight (January 27), in Tulsa, Okla., with Darius Rucker and Thompson Square sharing opening act duties. Keep track of their concert schedule here
