Miranda Lambert knows a great song when she hears it. But the talented singer admits that even she once let a hit slip through her finger.

"I had the song "Downtown" for a little bit," Lambert reveals to NOLA.com. "Me and Lady Antebellum had it at the same time, but they were cutting a record before me, so I just let it go, because I thought they would do an awesome job, and they did, and it was a big hit."

As the debut single from Lady A's Golden album, "Downtown" soared to the top of the charts in 2013. The trio, made up of Charles Kelley, Hillary Scott and Dave Haywood, knew early on that Lambert was interested in the tune.

“It was one of those songs that we heard and fell in love with and then found out that someone else had that song on hold,” Scott reveals to CBS. “That someone was actually a girl by the name of Miranda Lambert, who I consider a good friend.

“She very, very selflessly said, 'Let Lady A have it,’ so we owe her a huge thank you," Scott adds. “She really went above and beyond, and that’s what you find in our amazing genre of country music -- that the artists really do love each other and support one another.”

The threesome thought right away that the song was the perfect one to kick off their fourth studio album.

“When it was pitched to us, we thought, ‘Whoa, we would have never done that,’” Haywood says. “We wanted people to have the same reaction to it."

Lady A are undoubtedly having fun performing the hit tune as they cross the country on their Wheels Up 2015 Tour, but Lambert certainly isn't lacking hit singles herself. In addition to her past successful songs, she's in the Top 5 with her latest single, "Little Red Wagon." Lambert will kick off her own Roadside Bars and Pink Guitars Tour this fall.
