Quite the cross genre performance last night!

Fleetwood Mac's Stevie Nicks and three-time ACM 'Vocal Group of the Year' Lady Antebellum rocked Las Vegas last night! The American Country Music awards were handed out last night, featuring some great performances!

Nicks and Lady A sang the Fleetwood Mac hit 'Rhiannon,' as well as Lady Antebellum's latest hit, 'Golden.'

This isn't the first collaboration between the two. Last September Stevie Nicks and Lady A performed on 'CMT Crossroads.' They sang Lady A's 'Need You Now' and 'Just a Kiss.' They also rocked some Fleetwood hits like 'Landslide' and 'Rhiannon.'

Lady Antebellum will be in Bangor August, 30 with Billy Currington and Joe Nichols.
