The 38-year-old star will return to the US show and reprise her role as substitute teacher Holly Holiday for another episode, she recently revealed to Access Hollywood.
It is not yet known when the episode will be recorded or when it will air but she recently said her appearance in the show was 'the best job ever'.
Glee star Matthew Morrison told Access Hollywood earlier this year he enjoyed her cameo role.
He said: 'Gwyneth Paltrow is a genius. Who knew that she was such a triple threat? Great dancer, great singer, obviously a great actress - I just had the best time.'
