“hollywood at home” (8 p.m., hgtv): “Hollywood at Home” is a new special

“hollywood at home” (8 p.m., hgtv): “Hollywood at Home” is a new special that has celebrities welcoming us into their not-so-humble abodes. Among those giving tours: actress Andie McDowell, Olympians Natalie Coughlin and Carly Patterson, dance pro Mark Ballas and country singer George Jones.

“THE X FACTOR” (8 p.m., fox): Simon Cowell’s prediction was wrong. His new musical-talent show didn’t match “American Idol” in ratings mojo. Not even close. But it more than made up for it with an array of offbeat artists (including rappers), fiery feuds among the judges and plenty of compelling, tear-drenched drama. Now, the field finally has been whittled to some stellar finalists, and we’re about to find out who nabs that $5 million recording contract during a two-hour finale that is bound to be as bloated as it is glitzy.
