Courteney Cox is reportedly dating her “Cougar Town” co-star, Brian Van Holt, and her ex husband suspected there was something going on between them years ago.

Cox and David Arquette split up in 2010 but their divorce was just recently finalized, allowing Cox to go public with her new relationship with Van Holt. Though she hasn’t confirmed it herself, the duo were seen out and about in Hollywood on June 10, and a source has told “Access Hollywood” that the pair have been together for at least ten months. However, Arquette reportedly spoke about his split from Cox back in 2010 to Howard Stern, and said he thought she was having an “emotional affair” with Van Holt.

Indeed, onlookers said Cox’s daughter with Arquette, 9-year old Coco, seemed very at ease with Van Holt.

“The girl was extremely comfortable with Brian,” an source said of Coco. “She treated him like a dad or an uncle.”

Cox and Arquette haven’t said much about the dissolution of their marriage, although they are going to share parenting responsibilities for Coco. They cited “irreconcilable differences” as the reason for their split.
