Money Woes: 'Teen Mom OG' Star Amber Portwood Owes More Than $130K In Unpaid Taxes

After months of relationship problems with her fiancé Matt Baier, Amber Portwood is now in some serious financial trouble.

The Teen Mom OG star, 25, was recently slapped with a federal tax lien after failing to pay more than $130,000 to Uncle Sam, RadarOnline.com can exclusively reveal.

Indiana's Madison County Recorder's office confirms that the Internal Revenue Service hit the mother of one with the hefty lien on February 19, 2016.

The lien has not been released, the office claims, meaning there is no record that Portwood has paid any of the $134, 919.

The mom to Leah, 7, has faced money woes in the recent past. In January, she was sued for a nearly $1,500 medical bill, and she was nearly evicted from her Ingalls, Indiana, home in April 2015. (A source told RadarOnline.com at the time that she paid off her rent debt.)

But Portwood's problems pale in comparison to those of her fiancé Baier, 45, who as RadarOnline.com exclusively reported, owes financial support for at least nine secret children. Five of the baby mamas have sued him in Indiana court for an undisclosed amount.
