The morning show is known for its Halloween special and costume extravaganza. So hopefully McCord will dress up and join in the fun.
Also appearing on Monday's episode is actor/singer/host Nick Lachey, who will co-host "Live's" Halloween Headliner Ball with Kelly, according to the show's web site. Model/host Heidi Klum will be a guest.
"Live With Regis and Kelly" airs at 9 a.m. ET in most cities. To check local listings and network, click here.
