Much like Santa Claus, Paris Hilton spent a lot of time making her list and checking it twice - her guest list, that is! Yes, Paris threw a house party last night, and all the usual suspects turned up - Travis Barker, Brandon Davis, Nick Cannon, and on and on and on. We also caught Nicole Richie as she left - even though she sounded laid low by a cold (wear your socks, kids), Nicole still wished everyone happy holidays! (Lindsay Lohan, however, was most emphatically not invited by the hostess - whatever she did to Paris, it must have been spectacularly naughty!)

A sassy Paris Hilton gets dropped off at Teddy's by her casually dressed sister, Nicky and her boyfriend.

Paris Hilton does make-up application for an elderly friend at MAC Cosmetics, and then the crew heads to dinner at Newsroom Cafe in Beverly Hills.

I don't think anyone would call Paris Hilton a Scrooge (remember the Benjamin she gave the homeless guy outside of McDonald's?) but don't you find it strange that the heiress would go X-mas shopping for pals at the Bev Center's cheaper stores, like Wet Seal?

Looks like Paris finally had her fill of - last night, she made Stavros take her out for a real night on the town! The couple took in dinner and a movie - "dinner" courtesy of ritzy restaurant Katsuya, and "movie" thanks to Hollywood Video! (But Paris apparently likes to keep her options open - check out how many movies she pulls off the shelves!)

When we last left Paris, she'd just lost and then recovered her car keys - but if you thought that was her only run-in with an uncooperative lock that day, think again! Later that day, after picking up a few things at Fred Segal's and hitting the gym, Paris found herself face-to-face with a familiar adversary - the door to her house! (She eventually emerged victorious in time to get herself ready for her date with Stavros later that night - and yes, we'll have video of that in just a bit!)

Remember this sweet, innocent scene last week when Paris and Nicole went to visit Kris Kringle? Well we pointed it out then and it bears mentioning again in light of Nicole's arrest last night for DUI, that the girl had rolling papers in plain sight in her car that day. Now I've been known to enjoy a hand-rolled cigarette now and then but is that really why people usually by Zig-Zags?

Paris hit her favorite store, Kitson, to buy a gift for Britney's birthday today. And could it be that Paris is too cheap to buy even her own perfume? She sprayed on some Just Me by Paris Hilton from a tester bottle before checking out a pimp cup for Brit. She then headed to Kitson Kids across the street, amid a rush of paparazzi and even more annoying fans, to buy some goods for Britney's babies. Awww ...
