The next time your child refuses to make his or her bed, don't despair. You may have an artist on your hands.

A 16-year-old unmade bed, turned into an art installation, sold for $4,351,969 dollars at a Christie's art auction in London on Tuesday, according to Christie's.

Artist Tracey Emin calls it "My Bed," because it was the bed where she spent four days in 1998 "heartbroken and feeling terrible" she tells CNN.

Once Emin got out of the bed she recalls looking at the mess left behind and decided to make it art.

"Suddenly I had this vision of taking it out of the bedroom space and putting it into a white gallery space," she said. "It suddenly made sense," she said. "Wow this is fantastic artwork."

A year later, in 1999, "My Bed" was shortlisted for the Turner Prize.

It's not just the messy linens and blankets that bring the art installation to life. The objects surrounding it tell the story of a broken heart.

There's the ashtray overflowing with cigarettes, empty liquor bottles, dirty panties, bits of food, contraceptives and what appears to be a 16-year-old condom.

"It's like a piece of history, a time capsule," Emin said.

Art lovers agreed, and her unconventional sculpture sold for more than $1.7 million over the expected auction price, which was set between $1.3 million to $2 million.

Christie's won't comment on who bought "My Bed."
