We already knew that Oscar-winning Gwyneth Paltrow could act. Her excellent vocals in Country Strong and Glee showed us she could sing. Her bestselling recipe books let us know she could cook. But now we find out she can dance, too? It all seems a little unfair…

A just-revealed video, posted on LA-based personal trainer Tracy Anderson’s Instagram account, shows Gwyneth quite easily executing a complex dance routine to a hip-hop track, while smiling, laughing and barely breaking a sweat.

Dressed in a sports bra, leggings and day-glo sneakers, the 42-year-old exercise-lover was front row for her BFF Tracy’s class.

Gwyneth, who this year 'consciously uncoupled' from her Coldplay singer husband Chris Martin, recently laughed off criticism from TV chef Martha Stewart, who dismissed her lifestyle website, Goop.

'No one has ever said anything bad about me before,' Gwyneth drily joked. 'So I'm shocked and devastated. I'll try to recover.'

If anyone else bad mouths her, Gwynnie could always challenge them to a dance-off.
