Christie Brinkley Tax LienChristie Brinkley reportedly owes $531,720 in back taxes on her $30 million Bridgehampton, NY mansion. The IRS filed a tax lien against the 57-year-old former supermodel on November 21st.

Brinkley – who was once famously married to rock star Billy Joel – had been trying to sell the beach house that she lives in since 2008, but took it off the market in 2010. It is one of five homes that the Sports Illustrated cover model owns in the Long Island area.

A rep for the star told the media that “Christie Brinkley was surprised to hear today that a tax lien had been filed, and has instructed her team to resolve the matter immediately.”

The model and actress made her Broadway debut as Roxie Hart in the musical “Chicago” in April 2011. She reportedly has an $80 million fortune, which should make it easy enough for her to settle her hefty tax bill in a reasonable amount of time.
