Dancer Benjamin Millepied puts a smooth move on actress Natalie Portman over the weekend outside the Joyce Theater in Chelsea, where a European ballet troupe was performing.

Millepied, 32, a French-born dancer who appears with the New York City Ballet, is the choreographer on her new movie, “Black Swan” — but this is one quickstep that’s not in the script.

A week before their date to see the Gyor National Ballet from Hungary, the couple was spotted at a New Year’s Eve party in TriBeCa.
