SHORT CUTS

Alias scribes Monica Breen and Alison Schapker have inked a two-year deal with Touchstone, as part of which they will join the writing staff of ABC's Lost.... This Friday's Dancing with the Stars results show will be padded with performances by Michael Bublé (singing "Save the Last Dance for Me" and "Moondance"), as well as a display of quickstep by (yikes) host Tom Bergeron.... Sources tell the New York Post that Paris Hilton has been dumped by beau Stavros Niarchos (whose last name always makes me hungry for Mexican food).
