SARAH PALIN and TINA FEY

Fey opened the show on Saturday dressed as Palin, in a sketch alongside co-star Amy Poehler as Hillary Clinton.

Republican Palin was watching from home - and has since sent her approval.

Her spokesperson Tracey Schmitt says, "She thought it was quite funny, particularly because she once dressed up as Tina Fey for Halloween."
