Dave Haywood of Lady Antebellum shared a few more details about the trio's new album and Hillary Scott's pregnancy during an interview with WGNA radio recently. The band -- who will play the Taste of Country Music Festival in June -- has just released 'Downtown' as the lead single from a fourth album which Haywood says will follow suit.

"This will be more the party record," he tells the radio station's morning team, Sean and Richie. "A lot of songs we've been leaning towards for this record are kind of those roll down your windows, uptempo songs."

The ToC Music Fest -- booked for June 13-15 at Hunter Mountain in New York -- is the last date Lady Antebellum will play before Scott has her baby. Haywood revealed that she's due in July and the band will take a couple of months off before returning to the road later in the year.

Willie Nelson is another headliner at the ToC Fest and an artist Lady A teamed up with at the CMA Awards in 2012. Haywood admitted even country superstars were starstruck by the legend. "It's so funny, Tim McGraw, Keith Urban … everyone is getting their cell phone out taking pictures of Willie on their iPhone," he spilled.

In total, Lady A have just 10 shows scheduled for 2013, beginning with the San Antonio Stock Show and Rodeo on Feb. 16. Hunter Hayes and Trace Adkins are two of the other artists (over a dozen total) scheduled for the first-ever ToC Fest.
