How Only Taylor Swift Can Make This Baby Stop Crying

— -- Taylor Swift apparently has magical powers.

The pop singer, 25, posted an adorable video to Twitter Monday writing, "THIS IS THE BEST THING I HAVE EVER SEEN."

She was right.

The short clip shows a crying baby, who immediately stops once Swift's "Blank Space" comes on in the background. Then the music stops and the baby starts crying again!

The video info reads, "Rosie (6 months old) loves Taylor!"
