IS COURTENEY PLAYING WITH A FULL DECK?

Sitcom icon COURTENEY COX won’t make a move until she consults with her new psychic bestie — her tarot card reader — and friends fear he’s got way too much control over her life. “Everybody’s pretty shocked at how she has let this guy influence her decisions with the flip of a card or reading her astrology chart,” blabs an insider. And that’s not all. When she invites pals like

JENNIFER ANISTON over, she’s got tarot cards along with crystals and essential healing oils ready so they can join in. Jen and Courteney’s ex-hubby,

DAVID ARQUETTE, can’t figure out how the mystic managed to “become such a close adviser … but the actress swears she’s a lot less stressed these days because of his calming and knowledgeable presence.”
