During her performance at the MTV Video Music Awards on Wednesday night, Sabrina Carpenter kissed an alien, which left Britney Spears very confused. The singer reacted on Instagram yesterday to Carpenter’s dynamic medley of “Please, Please, Please,” “Taste” and “Espresso,” in which she paid multiple tributes to Spears.

In an Instagram story, Spears explained that she didn’t watch the VMAs but saw clips of the awards show online. “Did you guys watch the VMAs? I didn’t watch the VMAs but I saw YouTube footage of Sabrina Carpenter on my phone,” Spears said in the video. “Why is she kissing an alien on stage? I adore her. I love her to death. I didn’t understand that part. Why didn’t she kiss a girl? That was really weird.”

She continued, “But I also thought the whole thing was kind of weird… that Sabrina girl, she said my name on the red carpet and I thought that was kind of cool because sometimes I forget that I’m famous because I’m a mom, I’m kind of old, blah blah blah. But I thought it was kind of cool, that Sabrina girl, Carpenter. She said something and I was like, ‘Thanks, that’s cool!’ She made me cool.”
