Who doesn't love going to a great concert and then getting surprised by another great performer, who joins the one you're there to see? What about two additional unexpected performers? Well, Lady Antebellum's crowd got to experience just that last night (Feb. 22) at the trio's sold-out show at Nashville's Municipal Auditorium.

Not only did Lady A pull Luke Bryan onto the stage to help them perform his songs 'Do I' and 'Country Girl (Shake It For Me),' but they also invited Sara Evans onstage to deliver her tune, 'A Little Bit Stronger' -- a song which was written for her by Hillary Scott. As you can see in the clips below, the audience was more than thankful for the two-part surprise.

Tweeting about the show once it was over, Lady A said, "Nashville tonight was amazing. Thank you @saraevansmusic. Thank you @LukeBryanOnline." Then, this morning, they were still thinking back on the excited crowd and great company from the night before, tweeting "We are still so amazed at how wonderful last night in Nashville was."

Multi Grammy award winners Lady Antebellum are well on their way in their We Own the Night Tour, which will take them to the midwest this week with shows in Michigan and Indiana. The group, who seem to be amassing fans by the minute, will be touring heavily until the end of June. Who knows what other top-notch artists they'll be inviting out onto that stage?
