Brinkley, 57, said she regrets not paying more attention to her accounting, noting that she's been focused on her parents, who are dealing with "serious health issues."

The model has said she considers herself "lucky to have been employed" since she was 17 years old. And between her infomercials, real estate and modeling stints, she's still raking in the bucks. According to the Daily News, she is worth an estimated $80 million.

Brinkley made her Broadway debut this year playing Roxie Hart in the musical "Chicago."
