The actress, who was later charged with indecent exposure, was at her Tennessee home two weeks ago when she began arguing with her neighbour Carey Smith, reports mirror.co.uk.
According to Smith, who made a complaint to the police, Lien launched into a rant over one of her crying children.
She claims she then started swearing before lifting her shirt up to expose herself in full view of her children.
She told CNN affiliate WATE: “She started flashing and, ‘Woo hoo,’ and I said, ‘And what respect is that for kids?’
“There was none. And then she turned around and dropped her pants.”
When police turned up to her house to arrest her, Lien reportedly refused to put clothes on and had to be carried to the police car after threatening to kill the officers.
The 41-year-old has been in jail since her arrest on September 3 and her bond is set at $2,500.
