Adele has sold millions of albums in a week, taken off late-night TV and essentially dominated pop culture over the past month. Now, she has a Britney Spears co-sign.

The "…Baby One More Time" superstar posted a tribute to Adele on Instagram on Sunday (Nov. 29), with a video that finds her twirling in slow-motion to "Hello." Extra points for the grainy black-and-white filter used to evoke the song's music video!

"I could dance to this song a MILLION times...love you @adele!" Britney gushes. And if you keep replaying the Instagram clip, she really does dance to that song a million times!
