Christie Brinkley owes $531,000 in back taxes to the Internal Revenue Service, the New York Daily News reports.
The IRS filed a lien against the one of the properties the "Uptown Girl" owns on New York's Long Island Nov. 21, according to records obtained by the newspaper. Brinkley, 57, is reportedly worth $80 million, mainly from properties she owns in the Hamptons.

"Christie Brinkley was surprised to hear today that a tax lien had been filed, and has instructed her team to resolve the matter immediately," Brinkley's rep, Claire Mercuri, told the New York Daily News.
The former supermodel, who was once married to Billy Joel, made her Broadway debut earlier this year playing Roxie Hart in the musical Chicago. She recently reprised her role for the London production.
