Patrick Muldoon (ex-Austin, DAYS) stars in ALL ABOUT CHRISTMAS EVE, premiering December 9 at 9 p.m. ET/PT on Lifetime. Muldoon plays Tino, who runs a technology company with his partner Aidan, played by Chris Carmack. Haylie Duff also stars in the romantic holiday flick as Eve. "Tino has a great sense of humor and is woman crazy," describes Muldoon. "Even though he's a ladies man, he knows true love when he sees it, which is why he's trying to help his partner Aidan hook up with Eve." Former YOUNG AND RESTLESS actress Diana DeGarmo (ex-Angelina) also appears in the TV-movie, playing herself. ALL ABOUT CHRISTMAS EVE will air again on December 10 and 16.
