Lorde was performing at the Real Cool Festival in Madrid on Thursday and took some time during her set to speak out against AI glasses. While she didn’t specify any brands in particular, it’s likely she was taking a shot at festival sponsor Ray-Ban, which has collaborated with Meta on a pair of AI smartglasses.

The comments were captured in videos shared to social media. After thanking the crowd for being there and taking part in “something real,” she said that it was increasingly hard to know is and isn’t real, before saying “You don’t know if someone is wearing sunglasses or if they’re wearing those fucked up fucking… Can I just say, for the record, fuck the glasses. Don’t get the glasses. Not sexy.”

The comments come as Meta faces renewed scrutiny over its smart glasses. And, even in the face of that backlash, it is still reportedly planning to launch a pair of “super sensing” glasses that are continuously recording.

According to Stereogum, Lorde was followed on stage by Blackpink’s Jennie, who is a Ray-Ban Meta AI ambassador and has been featured in advertising campaigns on Instagram and in a video screened between sets at Real Cool.
