As part of the current "Mama Said" trend on TikTok, users post videos featuring Lukas Graham's 2014 hit "Mama Said," and share how they gave themselves permission to try something new because "mama said it was OK."
Earlier this week, Swift joined the "Mama Said" trend by posting a video of herself with the caption "Country Girls Can't Go Pop." Swift --who made her own country-to-pop crossover with the 2014 release of her album 1989 -- then shrugs, as the verse "Mama said that it was OK/ Mama said that it was quite all right" plays in the background. The video then flashes several images of Twain (whose 1997 album Come On Over was a crossover smash, certified 20-times platinum by the Recording Industry Association of America, and is among the best-selling albums of all time). A few final shots show Swift and Twain hugging one another, as well as an image of them onstage at an awards show.
