NEW YORK (AP) _ Exercise, eating vegetables and avoiding too much sun are some of the beauty secrets cited by the women lauded as the world's 10 most beautiful by Harper's Bazaar magazine.

Singer Diana Ross says freeing the mind of bitterness is her key to inner and outer beauty.

Rebecca De Mornay, of ''Risky Business'' and ''The Slugger's Wife,'' says working out helps her keep her good looks. Catherine Oxenberg of ''Dynasty'' eschews red meat and alcohol, while Connie Sellecca of ''Hotel'' stays out of the sun to keep a clear complexion.

''Dynasty'' star Linda Evans says in the magazine's September issue that she stays attractive by meditating. Model Cheryl Tiegs says daily weigh-ins remind her to keep slim, and TV journalist Barbara Walters is wild about very light pink nail polish.

Isabella Rossellini, daughter of Ingrid Bergman and Roberto Rossellini, plays makeup tricks, such as doing ''a very strong red mouth and nothing at all with my eyes.''

Teen-age actress Molly Ringwald, star of ''Sixteen Candles'' and ''The Breakfast Club,'' says her curly red locks come ''straight from the bottle.'' Former ''Charlie's Angels'' star Jaclyn Smith recommends an overnight treatment of castor oil or petroleum jelly on eyelashes.
