Princess Beatrice and Princess Eugenie were totally stoked to meet Glee star Chris Colfer at the recent Hard Rock Calling festival in London.
Chris's character Kurt is obsessed with the British royal family, and The Sun report he is begging Glee producers to write a storyline involving Fergie's daughters.
"The princesses love Glee," Chris said after meeting them backstage.
"We've got the royal seal of approval. Maybe we can get them a cameo on the show. Wouldn't that be amazing?"
An eyewitness said the princesses looked "a bit bedraggled from all the rain but they soon perked up after they saw Kurt was there.
"Eugenie especially is a huge fan of Glee and everyone got on like a house on fire. It was a real party atmosphere.
"Eugenie was pressing Chris for more information on the third series of Glee, which has been filmed but not aired over here yet."
The same source spotted Prince Harry at a festival afterparty, noting he "really got the party going. A lot of tequila was about."
