It's one "performance" that's not going to earn Kim Delaney any medals.
The Army Wives
star appeared to veer off script during a protracted and, at times, incoherent speech Thursday night at Philadelphia's National Constitution Center at the Liberty Medal Award presentation to former defense secretary Robert Gates.
The actress, 49, fidgeted at the podium as she told crowd members how she "served in active military duty family for five years" and went on to say how she "attended numerous military funerals, including that of my best friend's son."
After pausing, Delaney then explained to the crowd, who sat in stunned silence, that she in fact was talking about her role on the Lifetime television show, though she noted her father was a Korean war veteran.
According to a local ABC news affiliate, Delaney, 49, was escorted off the stage before she could finish her speech.
In 2002 the actress was arrested on suspicion for drunken driving
after refusing a breathalyzer test. She later pleaded no contest. She has also reportedly entered rehab for alcohol addiction twice.
Reps for the actress could not be reached for comment.
