The members of Lady Antebellum have developed some amazing friendships and relationships among their peers, and many of them have turned into songwriting partnerships, as well. Lady A's Charles Kelley and Dave Haywood forged a deeper connection with Luke Bryan when they co-wrote his No. 1 hit, 'Do I,' and the trio has been writing and collaborating with such folks as Blake Shelton, Miranda Lambert and R&B singer John Legend. Charles has even been trying to get together with Ronnie Dunn to pen a song or two.

One of the songs Lady A's Hillary Scott co-wrote with Miranda, titled 'Suffocating,' has ended up on Blake's upcoming album, his second SIX PAK, expected in stores later this year. "We actually wrote it on the Kenny Chesney tour this past summer," Hillary tells The Boot.

"It was one of the many nights I hopped on her bus and we stayed up late just drinking wine and playing music and writing music. And I actually sang background vocals on Blake's cut of that song, and I'm looking forward to hearing it. He sang the crap out of it from what I heard in the studio ... it's a real passionate number."

Lady Antebellum are currently hanging in the Top 10 on the country charts with their latest hit, 'American Honey.'
