The actress best known for playing Detective Diane Russell on the drama television series NYPD Blue, delivered an incomprehensible speech at Philadelphia's National Constitution Center Thursday night and was kicked off the stage during the Liberty Medal Award Ceremony to former defense secretary Robert Gates.

Delaney was a complete embarrassment as she slurred and uttered inappropriate and incoherent sentences about having served in active military duty family for five years.

I've seen soldiers come home with painful life altering injuries borne of their time and service, she said, slurring. I've attended numerous military funerals, including that of my best friend's son.

The problem, apart from the rambling, was she hasn't done any of these.

It's all make believe. I do that as a job. It's make believe, she said nearly two minutes into her speech. I have the luxury to do all of this on a television show.

She was escorted off stage before she could finish her speech as the audience started growing increasingly uncomfortable.

The 49-year-old actress who stars on the Lifetime television drama, Army Wives, has a history of substance abuse. In 2002, Delaney was arrested in Malibu, California, for suspicion of drunk driving after she refused to take a breathalyzer test. She subsequently pleaded no contest and was sentenced to two-years probation, fined, and ordered to take a defensive driving course.

According to an ABCNews report, the National Constitution Center or representative of the actress hasn't responded to the incident.
