Jessica Simpson Says Marriage to Nick Lachey Was One of Her Worst Financial 'Mistakes'

The fashion mogul told CNBC that her first marriage might have been among her worst 'money mistakes.'

Jessica Simpson's clothing and accessories line celebrated its 10th anniversary this week. The 35-year-old fashion mogul, whose company is valued at over $1 billion, sat down with CNBC's Closing Bell on Thursday, and revealed that her worst financial decision might have been getting married to Nick Lachey.

When host Kelly Evans asked Simpson to name one of worst professional missteps of her life, Simpson laughingly replied, "Biggest money mistakes? I don't know. For some reason I thought of my first marriage!"

Evans replied, "That's actually a common answer, believe it or not." After all, divorce can be quite expensive.

Simpson, who is now married to 35-year-old former NFL pro Eric Johnson, tied the knot with Lachey in October 2002. The couple announced they were separating in November 2005, and Simpson filed for divorce the next month.
