6. Cher (65)
What more can you say about this woman? She’s done it all and then some. Perhaps her biggest achievement is the fact that the world is still curious to see what she does next. While divas half her age have been banished to the wilderness of the adult contemporary market, the Burlesque star remains a pop culture phenomenon. When not beefing with the likes of Nicki Minaj on Twitter, Cher is busy putting the finishing touches on her long-postponed Lady Gaga duet and plotting her September world tour.
