The music video for the upcoming film Nine has just come out, and we’ll just say we understand what A-Rod sees in Kate Hudson.

She carries the trailer, singing on stage in a short silver flapper-style outfit as she performs.

The preview shows cameos by Fergie, Penelope Cruz, Nicole Kidman, and Marion Cotillard, all of whom are romantically involved with famous film director Guido Contini, played by Daniel Day-Lewis.

The film opens on Christmas Day.
