Loretta Lynn, Heart, Norah Jones, Cat Power, Sia and the Gossip have all been added to the 2010 Lilith Tour.

The most exciting addition is, of course, Lynn, the pioneering country singer to whom all the ladies on the bill owe a debt of gratitude for helping pave the way for female artists.

"I'm happy they wanted me on this Lilith tour,” said Lynn in a statement. “I have never done shows just with other girl singers before. When I first started out, they said girl singers couldn't sell records or concert tickets. We've come a long way since then and we're gonna have a big time out there!"

No word yet on how many dates Lynn—or any of the new additions-- will do. In fact, we’re still waiting for dates for the tour. But in the meantime, Lilith has dropped the word “fair” from its title and added 15 more cities to the originally announced slate of stops: Edmonton, San Diego, Phoenix, Salt Lake City, St. Louis, Indianapolis, Detroit, Hartford, Raleigh, Charlotte, Nashville, West Palm Beach, Tampa, Houston and Austin.
