HOT HALLOWEEN PARTY: Club Marcella's four-day (Saturday, Sunday, Tuesday and Wednesday) funfest, complete with a costume contest and a spooky hair-raising maze.
HOT POP-STERS WITH INDUSTRY CLOUT: 'N Sync and Britney Spears, the highest-ranking musical acts on Entertainment Weekly's annual Power List of influential folks in showbiz.
HOT I'M-REALLY-NOT-CRAZY COMEBACK: Mariah Carey, who appears tonight at 8 on ABC's "2001 Radio Awards" and will do a guest spot on "Ally McBeal" in January.
NOT HOT: "Faith of the Heart," the roots rock theme to the otherwise cool "Star Trek" spin-off "Enterprise." Let's hope this grating slice of Springsteen-lite gets lost in space.
