Last week, Cox, 46, and Hopkins, 40, were spotted in Hawaii, but the two were filming on location for their ABC sitcom.

"They are strictly, strictly platonic," a source told Us magazine, adding of Cox, "She's close to her co-stars. She's been like that since 'Friends.' But there's nothing more going on."

Also on the trip was the actress' 6-year-old daughter, Coco.

Cox and actor David Arquette announced their separation in October.
