Paltrow has been a popular guest on the musical series' current season, playing substitute teacher Hollie Holiday, and teased that the character may feature in some way on the tour.
"Possibly - they've asked me to do a couple of little surprise things," Paltrow let slip to BBC2's Something for the Weekend.
Since appearing on the Fox series there have been various reports that Paltrow has already signed a solo record deal, but the actress insisted that she is still considering her options and would only release an album in "the right way".
The Glee tour is due to hit the UK in June and July with several dates across Manchester, Dublin, and London.
Glee continues to air in the US on Tuesdays at 8.7c on Fox and in the UK on Mondays at 9pm on E4.
