Actor RUPERT EVERETT hated having to don fake breasts for his role as a school headmistress in new movie ST. TRINIAN'S - because the heavy padding gave him severe back pain.

The gay star plays Carnaby Fritton in the British comedy, but admits the cross-dressing caused him to suffer for his art.
He says, "I had these enormous double D cup breasts. They put my back out.

After filming finished I had to lie down."
