UPDATE: IRS Files $500K Lien on Christie Brinkley's Bridgehampton Estate

The IRS has filed a $531,720 federal tax lien against model and actress Christie Brinkley's Brick Kiln Road estate in Bridgehampton, according to Suffolk County clerk records.

Brinkley has had liens filed against her in the past from private companies, but this is the first tax lien for her in Suffolk, according to county records. Past liens have been from pool and landscaping companies.

She owns multiple parcels in the Hamptons, where she is frequently seen at fundraising events.

Brinkley responded to the news in a post to her Facebook wall on Sunday:

"I have worked hard, and consider myself very lucky to have been employed since I was 17 years old," she wrote. "I have also dedicated time energy and resources to giving back as much and as often as possible. I have never had an issue with the IRS. I never intended for my tax returns to be filed late, and I was surprised to learn of it online, on Friday, Dec. 2. I immediately instructed my accountants to remedy the situation, which for most people is a private matter. I regret not paying more attention to my accounting, but I have been and remain focused on my whole family as both my parents navigate serious health issues. There have been slanderous and false accusations associated with this report and it's the collateral damage to my family, friends and fans that hurts me the most. I am confident that this too shall pass and I am grateful for outpouring of understanding and support I have received."

According to the IRS website, a notice of federal tax lien may only be filed after the target has been notified of the tax liability and neglected or refused to fully pay the debt within 10 days.

The lien was filed Nov. 21.
