Montell "This Is How We Do It" Jordan owes quite the sum to the IRS, who filed a tax lien to the former R&B star in 2004. It turns out that he owes some $627,987.06 in back taxes from the years 1999-2001. If he doesn't pay up soon, the IRS could start to snatch up his property to get their money. Ouch. Hopefully dude can get this straightened out.
