Taylor Swift casually debuted her diss track “thanK you aIMee” (which is rumored to be about Kim Kardashian 👀) to crowds at London's Wembley Stadium on Saturday night (June 22) and a fan (bless them!) had the *chef's kiss* idea to pan their phone over to Tay's mom Andrea Swift. Like, specifically to catch her reacting to the line “Everyone knows that my mother is a saintly woman / But she used to say she wished that you were dead.”

Yep, Andrea was filmed straight-up clapping and cheering during the “saintly woman” line, which is honestly very cute.

ICYMI, Tay introduced the track by thanking people who “talk shit” about her, saying in part, “It really makes me think about how every time somebody talks shit, it just makes me work even harder and it makes me that much tougher. So, it also makes me incredibly thankful for those people.”

Meanwhile, back in April, a source told People that Kim is “over” the drama between her and Taylor, thinks the singer “should move on,” and “doesn’t get” why Tay “keeps harping on it” since it's “been literally years.” Okay then!

An Entertainment Tonight insider also said that “Kim has moved on from the Taylor feud and doesn't care about her song 'thanK you aIMee.' She has put it in the past, especially since their drama happened so long ago. Kim respects Taylor as an artist but doesn't have a strong desire to settle their differences right now.”

Oh, and ANOTHER insider got in touch with Us Weekly to give Taylor's perspective, saying “thanK you aIMee” is her “final word” and that she “has not heard” from Kim about it. Noted!
