Gwyneth Paltrow lays on top of a piano

Gwyneth Paltrow writhes (or at least lays) on a piano as CeeLo Green (hidden under feathered costume) sings along on The 53rd Annual Grammy Awards. The date was February 13, 2011, and the song they sang was Green's hit "Forget You." Gwyneth Paltrow was born in 1972, so she turned 39 the year of this performance.
