Don't believe everything you read: Jennifer Lopez is not pregnant. "Absolutely 100% false," she tells December's Harper's Bazaar, on stands Nov. 20.

Lopez, who is married to Marc Anthony, says she "is not getting in vitro," either.

Lopez graces the cover of the mag's annual best-dressed issue and says she's enjoying a hats-and-head-wraps phase. "They remind me of Audrey Hepburn, Ingrid Bergman and Lana Turner old Hollywood."

From Lopez to Kate Moss, HB kicks off the year-end inventory season with a list of Hollywood's best-dressed. All 54 of them.
