Sofia Vergara Wails To Writers: ‘Butt Floss? What Eez That?’

Sofia Vergara and Ed O'Neill

SOFIA VERGARA’s an American citizen now (welcome, chica!) but the Colombian-born bombshell went no comprendo over a kinky joke penned by “Modern Family” writers!

Said my source: “After Sofia’s character, Gloria, went shopping at expensive stores, hubby Jay, played by Ed O’Neill, rummaged through her bags, found a skimpy pink thong … with ‘Butt Floss’ written on it.

"The joke was lost in translation for Sofia until Ed explained, ‘it’s like, ya know, tooth floss – but for your BUTT!’

"Even after Sofia got it, she and Ed kept cracking up at the joke, ruining take after take!”

Furious bosses – panicked over overtime – roared onto the set, raging that their next take had better be PERFECT … no ifs, and or butts!
