A Christmas Eve night out with best pal Courteney Cox has wrecked a news exclusive claiming Jennifer Aniston is pregnant. The National Enquirer reported that Aniston, 38, is expecting, but her publicist has denied the rumor.

In a simple statement, he says, "She is not pregnant."

And the story seems to have fallen flat around Christmas - Us Weekly magazine reports Aniston was spotted drinking martinis at Mastro's in Beverly Hills with Cox and her husband David Arquette on December 24, a week after the actress had her hair colored by stylist Michael Canali.

Both drinking and hair dying are strict no-nos for expectant moms.
