The 38-year-old actress says she just reunited with her children in London and couldn't return to Los Angeles for Saturday's Creative Arts Emmy Awards, where TV guest roles are honored.
Paltrow would, however, return to "Glee" to reprise the free-spirited substitute teacher Holly Holliday, if invited. She says she "loves doing that show" and Holly is "probably the most fun character I've ever gotten to play."
Meanwhile, Paltrow has been busy promoting her latest film, "Contagion," where her role was probably NOT the most fun character she's ever gotten to play. She's Patient No. 1 in a killer pandemic.
