The singer plays Jenny, a mysterious woman who will play a special role in Will’s life. Will&Grace tells about the friendship between the neurotic Grace (Debra Messing) and her gay best friend Will (Eric McCormack). The series helped two decades ago to make commonplace for LGBT characters on American television. The series made a restart three years ago, with moderate success. Nevertheless, channel NBC has decided to stop the series again after three new seasons. The last series has eighteen episodes and is expected to be shown halfway through the coming TV season.
