Happy birthday, Lady!

Country star Hillary Scott of Lady Antebellum was surprised Thursday with a birthday cake following her band's rehearsal for their performance on the Academy of Country Music Awards in Las Vegas. Scott, who turned 23 on Wednesday, will continue celebrating Friday night with pals including Miranda Lambert, Blake Shelton and Dierks Bentley at a birthday bash in a Vegas club.

Scott and fellow Lady A members Charles Kelley and Dave Heywood vie for the top vocal group award on Sunday's show. Last year, the band scooped up the ACM's top new vocal duo or Group. – Eileen Finan
