It looks like Jennifer Aniston's unlucky love streak may be rubbing off on Courteney Cox and husband David Arquette, who seem to be going through a tough time, according to Star magazine. Recently, Courteney and David have been spotted solo; Courtney at Malibu’s Nobu on Feb 17 with single gal pals Sheryl Crow and Jennifer Aniston, while the night before David was seen at an NBA Celebrity Tournament in Las Vegas.

Things seem more suspicious when Cox was spotted with Dirt co-star, Josh Stewart, shooting pool at W. Hollywood’s Barney’s Beanery. Courteney’s new show seems to be her main focus which she and David “had words about.”

A source adds, “When Courteney isn’t on the phone with someone connected to the show, she’s going off to meetings or hanging out with cast members socially.” David and Courteney were once referred to as the oddest couple in Hollywood, and while opposites may attract, the differences of these two may pull them apart. “Sometimes when you get to know someone so well, what was once endearing just becomes irritating.”
