Miranda Lambert treated the CMA Fest crowd to a special surprise on Friday night.  She brought Avril Lavigne on stage . . . and they performed a couple of songs together.

They started with Miranda’s ‘Kerosene’ and segued into Avril’s pop-punk classic ‘Sk8er Boi’.

Lavigne showed off her country attire in a TikTok set to Lambert’s music.
