Tilda Swinton and Donald Trump fighting. So are Tori Spelling and Star. And, yes, even Gore Vidal and Ed Koch. But at least there's some love: Heidi Klum and Seal had baby number four. Welcome to your Tuesday gossip roundup!

  • Oh, it's on: Tilda Swinton has joined a fight against Donald Trump's latest golf course, which would be built on the Scottish coast and would displace residents. Trump's people responded by calling Swinton and other protesters "extremists." We imagine Swinton can get a bit more extreme than a petition. She looks sweet, but we see some crazy in those eyes.

  • The ever-fecund Heidi Klum gave birth to her and husband Seal's fourth child, a girl named Lou. Klum's probably too exhausted to speak, so Seal released a statement wondering — and explaining — how he found even more love in his heart for the new tot. We could try to be cynical about this, but good golly, Seal and Klum just too darn adorable. [People]

  • Carrie Underwood will host a two-hour holiday special that will feature Dolly Parton and David Cook. Because, you know, all the other recent variety shows have done so well. [Reuters]

  • Remember when Tyra Banks told us all to kiss her fat ass and stop discussing her weight because she loved herself and all that? Well, now she's dropped four dress sizes. Body confidence must be out this season. [Daily Mail]

  • In other weight-related "news:" Star magazine had an expert say that Tori Spelling's only 95 pounds, so Spelling tweeted that she's 107 pounds and the tabloid can weigh her if they want. The aforementioned expert, meanwhile, says that 5'5" Tori's still 13 pounds shy of "remotely healthy." These weight wars sure can be ugly, huh? [Star]

  • Madonna's former trainer, Tracy Anderson, will have to defend herself against a $1 million lawsuit filed by an ex-boyfriend who swears she used her feminine wiles to put a curse on him and make him spend his money on her business. He also claims she made up big, fat whopping lies, like that she had been in Cats and was a Power Ranger, all easily verifiable facts. [Page Six]

  • Paul Anka will receive 50% of the publishing rights from Michael Jackson's new track, "This is It," because he helped write it. [TMZ]

  • Joe Francis participated in last weekend's gay rights march in DC not because he wants to get good press, but because knows the pain of being dogged by the religious right and can therefore empathize with the same-sex crew. Um, really? [Page Six]

  • Some say gay writer Gore Vidal's an anti-Semite, which explains why people such as former NYC mayor Ed Koch are furious he'll speak at the famously Jewish 92nd Street Y next week. Koch, who some say remains closeted, remarked, "Those who invited him are, as Jews, either most forgiving, or schmucks. The latter word is intended to cover masochists." [Page Six]

  • Are you an Elvis fan with cash to burn? Well, you can bid on a lock of the singer's hair at an auction. It's expected to sell for at least $8,000. [Reuters]

  • Can you believe it? A Los Angeles doorman didn't recognize Whitney Port and she had to wait in line for a half-hour until someone set him straight. Oh, the indignity! [Page Six]
