Colin Firth is coming to my toilet.

Because of his quickie in “Austenland,” opening Friday, life-size thick cardboard Colin mock-ups will decorate theaters. He’s 6-foot-1 1/2, 177 pounds, shoe size 12, statistics of other assorted parts — this I don’t know.

I wanted him. Management is sending him — or it — to me. Life-size cutout Colin Firth will stand in my john.

Keri Russell, the film’s gorgeous star, is delicious. “I look glamorous because someone did my makeup,” she grinned. “Truth? I live a simple life.

“Home’s Brooklyn with my husband who does construction. Our son’s 6, daughter’s a year and a half. I take them to school. I feed my cat Finn.

“I’m skinny because of my dad’s side of the family. He was a dancer. I’m a nerd who works out. Bikes. Shops for groceries and nobody stares, cares or bothers about me there — except a hardhat the other day who yelled, ‘Hey, you kick ass.’ ”

Star of FX’s series “The Americans,” her eyelashes reached Coney Island. She wore Saint Laurent rhinestone studded ($1500-ish) stilts. She did “Austenland” two years ago “while I was pregnant. We lived on the Getty estate south of Oxford, 45 minutes west of London, with pheasants running around.”

Simple unglamorous size zero nerd. Right.

She only didn’t have Colin Firth. Me, I have him.
