Da que pensar que Britney haya twitteado este articulo de opinion sobre el videoclip diciendo que es el que mas le ha gustado

"Even though she doesnât need to prove it to anyone (or ever dance again, really), Britney danced. It was the hardest sheâs done in years. Sure, it wasnât THE MOVES that we once got, but sheâs visibly putting in effort again â she worked, bitch. There was floor choreography. Iâm not here to hear complaints: Those who whine about the loss of âIâm A Slave 4 Uâ-era Britney are the same ones who likely bemoan the lack of music videos on MTV. We get it already. Grow up, get over it and realize that there is still a VERY MUCH AMAZING pop star in front of them, still working (bitch) and remaining the best pop star in the world."
