Gwyneth Paltrow is in a New York studio doing a remix with Cee Lo Green of “Forget You,” his song that she performed on “Glee.” Sources said the pair are working with Bruno Mars‘ producer, Ari Levine. We’re told they went back to work on the track “since everybody thought she rocked it on ‘Glee.’ ” Green recently hinted that he and Paltrow would collaborate on something “extra-cool” in the future. And the two will also appear together on the Jan. 15 broadcast of “Saturday Night Live.” Paltrow’s rep didn’t get back to us.
