Even thought it won't premiere until April, HBO ran an extended preview of their new fantasy series Game of Thrones last night. In this clip, actors and producers fill in some of the details of the backstory.

• There's both good and bad news for Mischa Barton. The bad: She's reportedly drinking again and was seen "knocking back shots and drinking margaritas" earlier this week. (As you may remember, that sort of behavior led Mischa to spend some time in the hospital this past summer.) The good news: She supposedly looked "healthy" and "in control" while doing it, so it should be a few months before she hits bottom again and is forced to make a return trip. [P6]
• Think a good thought for Madonna. Louis Vuitton has decided to drop Madge as the face of the brand and replace her with 25-year-old supermodel Lara Stone. [Sun]
• The last 24 hours of Tiger: Holly Sampson, the porn star who had been suspected of having a tryst with Tiger, confirmed the rumor yesterday; meanwhile, Hollywood madam Michelle Braun says Woods spent $60,000 on hookers between 2006 and 2007, was into the "college cutie, girls-next-door look," and was a fan of three-ways, too. Luckily for Tiger, the reports about his dozen or so mistresses (and all the kinky specifics) may not spell disaster for his marriage to Elin Nordegren. Several tabloids report that Woods has come clean to Elin about "all" of his misbehavior in recent days and she's planning to stay with him.
