Courteney Cox is reportedly moving on from her marriage to ex-husband David Arquette with her Cougar Town co-star Brian Van Holt.

This latest round of rumors that they’re dating come about two years after Arquette told Howard Stern that Cox was having an “emotional affair” with Van Holt. Cox and Arquette split in 2010.

“They've been going out for about six months," a source told Us Weekly. They feel more comfortable being out in the open with their relationship now that Arquette has gone public with his girlfriend, Christina McLarty.

Sources say they "acted like boyfriend and girlfriend" during a recent dinner outing. "The girl was extremely comfortable with Brian," an onlooker said of Cox’s 9 year old daughter Coco. "She treated him like a dad or an uncle."

Digital Spy reports Cox and Arquette finalized their divorce in May after being separated for two years.
