Pop powerhouse Kelly Clarkson has been added to this summer’s Lilith Fair, helping to equalize the previously announced Ke$ha. Clarkson joins a number of other acts that have been announced for the female-focused festival, including Colbie Caillat, Tegan and Sara, The Bangles, The Go-Go’s, Jill Scott, and founder Sarah McLachlan. The fair, which took place for three straight summers from 1997 to 1999, is being revived this year, though tour dates have not yet been announced. [MTV News]
