Cox has yet to offer details as candid as Arquette's. According to RadarOnline.com, after their separation, she may be engaging in a more-than-professional relationship with her "Cougar Town" co-star, Brian Van Holt, 40.
Arquette's current fixation appears to be Waltz, a 28-year-old lithe brunette who could serve as Megan Fox's stunt double (and for that matter, looks not unlike a younger version of Cox). Waltz has been romantically linked to a number of celebrities, including Ryan Seacrest, Chris Pine, Jesse McCartney and Paris Hilton's ex-boyfriend, Doug Reinhardt. She's also infamous for reportedly punching Lindsay Lohan at a Hollywood nightclub in July.
