While talking to Variety about moments that defined pop culture at awards shows, Eilish and her brother, Finneas O'Connell, briefly discussed the Franc Fernandez "Meat Dress" that Gaga wore to the MTV Video Music Awards in 2010.
"I grew up watching the GRAMMYs, we all did. I used to judge all the girls' dresses. That's all I did, I barely paid attention to the music," Eilish said, to which O'Connell then asked, "Was the meat dress a GRAMMYs event?"
"Eh, Yiiiiikes," Eilish, a known vegan, responded. Watch around the 3:15 mark:
Some of Gaga's fans who watched the video took the reaction as a diss, creating a #BillieEilishIsOverParty on Twitter that quickly started trending.
