Actress Courteney Cox has ended her relationship with actor Brian Van Holt, according to her ex-husband. David Arquette broke the news of the split during a boozy phone call to pal and radio shock jock Howard Stern's show on Wednesday (30Oct13). Initially hesitant to share details on-air, the actor said, "I'm not going to get into her personal stuff," but he revealed Cox has already moved on with someone new. He said, "She's with someone who loves and cares for her. That's all I care about. She's the most brilliant, beautiful friend that I've ever met." Cox and Van Holt reportedly began dating earlier this year (13). Arquette accused the actress of having "an emotional affair" with her Cougar Town co-star in 2010, shortly before they separated after 11 years of marriage. Their divorce was finalised in May (13). The actor's drunken call to Stern surprised many fans as Arquette has been sober for almost two years after checking into rehab at the beginning of 2011 for alcohol-related issues.
