Kate Walsh is an American Idol

Kate Walsh is all smiles as she prepares to depart on an early morning flight from LAX Airport in Los Angeles on Tuesday (May 26).

The 41-year-old Private Practice star was at the American Idol finale last week, clapping and dancing along to all of the performances. Watch the video below!

Last week, it was reported that Kate‘s estranged husband, Alex Young, subpoenaed Stephen McPherson, President of Disney/ABC Television, for a deposition — to testify what he knows about Kate and her finances.
