The "Kerosene" singer showed an equal amount of love for her pal, sharing a photo of Twain riding high above her audience on a crane covered by a fringe saddle, which is also known as a heavy dose of country swag.
It seems the show was exactly what Lambert, 31, needed. She added a few hashtags to the picture, but the most poignant one was the last: Music is medicine.
BFFs have been featured heavily on Lambert's social media since her divorce from husband Blake Shelton. Earlier this week, she shared a photo with a pal and thanked Jesus for coffee, girlfriends and concealer, and she's also been both hanging out with her friend Ashley Monroe and promoting Monroe's new album -- as has Shelton.
Lambert has always been a big supporter of not just the main gals in her life but all women in music. Back in May, Lambert, who is also part of the trio Pistol Annies with Monroe, tweeted that she will always "do everything in my power to support and promote female singer/songwriters in country music. Always."
