While David Arquette has been linked to Hollywood hanger-on Jasmine Waltz, a new report claims that Courteney may have been involved her TV co-star Brian Van Holt.

Brian Van Holt, who actually plays Courteney Cox’ ex-husband on ABC’s Cougartown, may have spent the night in Courteney’s bungalow, leading to the breakup of Cox and now-estranged husband David Arquette‘s marriage.

RadarOnline.com reports that Van Holt and Cox may have spent a night together on the set of Cougartown in April, when rumors were swirling that the two were an item.

On the other hand, a source on the set of the show tells us Cox actually spends a great deal of time in her bungalow, and that it would be “news” to him that the two were hooking up.

Cox, 46, and Arquette have been married for even years and have a six-year-old daughter. The Hollywood couple released a statement last night saying, “We remain best friends and responsible parents… and we still love each other deeply.”
