Former Dynasty diva Joan Collins (now slumming it on CBS's Guiding Light) is taking potshots at Dolly Parton. In an interview with the BBC, the 69-year-old actress explained why she's no fan of plastic surgery: "Dolly Parton has a face like a doll, you know, it doesn't look right to me." So, what's her secret to staying so young and hot? Sex! "[It's] one of the best and cheapest beauty treatments there is." So much for Oil of Olay!
