• Dina Lohan, America's No. 1 mom and the face of a new line of shoes, is defending Lindsay against her dad's accusation that the actress is addicted to drugs and desperately needs an intervention. ("I have no idea what he is talking about," Dina says.) She also stood up for LiLo's fashion design skills, even after her debut as Emanuel Ungaro's "artistic adviser" was savaged by the press earlier this week: "The critics can say whatever they want, but Lindsay is a genius," she said. [P6, NYDN, Radar]
• Mischa Barton reportedly "had a drink in hand all night" on the LES on Wednesday, where she was seen buying shots for Young Veins' frontman Ryan Ross. Where's Michael Lohan when you need him? [NYDN]
• Meanwhile, model Agyness Deyn is reportedly laying off the booze in solidarity with her boyfriend, Albert Hammond Jr., who is in rehab. [P6]

Kelly Bensimon has odor issues. Marge Simpson will have a 3-page Playboy spread. Isaiah Washington's still having a hard time finding work. And Nicolas Cage has a lot of money the government wants. Enjoy your Friday morning gossip roundup!

Over the weekend, the New York Times thoroughly dissected the three wedding registries set up by Ivanka Trump and Jared Kushner, who plan to tie the knot at the end of the month at the Trump golf course in Bedminster, NJ. The attention sure seems to have paid off: All the unsold items at Crate & Barrel and Tiffany mentioned in the article have since been spoken for. But it also looks like the couple wasn't especially thrilled to have their drinking glass and serving spoon preferences revealed to all. You'll need to obtain a password from Jared or Ivanka to view their Williams-Sonoma registry from now on. [NYT, previously]

Nuns don't understand Lady Gaga. Small children understand Michael Jackson and Heath Ledger's deaths. And Martha Stewart can't comprehend Jessica Simpson's dead dog surprise. Welcome to your Friday gossip roundup!

• Ivanka Trump has a set a date for her wedding to real estate scion Jared Kushner. It will go down on October 25 at—where else?—the Trump National Golf Club in Bedminster, NJ. Mark your calendars! [P6]
• Emma Watson is doing her best to "blend in" now that she's a freshman at Brown. Which is a little hard to do when you have the paparazzi tracking your every move on campus, clearly. [NYDN]
• The Olsen twins will be bartending this evening at Barneys as part of the festivities planned for Fashion's Night Out. So Mary-Kate must have just been training the other night when she was spotted "chain-smoking and throwing back shots." [P6]
• Ellen DeGeneres has been tapped to replace Paula Abdul as a judge on the ninth season of American Idol. [E!]

• Lindsay Lohan left her cell phone at a deli yesterday. When she returned a few minutes later to retrieve it, an employee refused to give it back to her. LiLo wasn't too pleased to hear that, of course. (Let's hope the Italian ice she's holding made up for it.) But most of the time, she only has herself to blame for her troubles. Yesterday she tweeted that she was at a store in SoHo. But then she got annoyed when a gazillion photographers materialized outside a few minutes later. [Sun, P6]
• Salman Rushdie was spotted making out with a hot, young babe at the Inglourious Basterds party at the Standard Grill the other night. [P6]
• Jennifer Aniston supposedly "feels rejected and upset" after Bradley Cooper dropped her and started dating Renee Zellweger. [Us]
• Speaking of Zellweger, she used her appearance on David Letterman's show last night to promote the Blue Parrot, the Mexican restaurant she co-owns with Ron Perelman, Jon Bon Jovi, and Larry Gagosian, among others. [People]

"I saw Jared Kushner and Ivanka Trump having lunch today at the '21' Club," a tipster tells us. "They were with two other people. Not sure who the others were." The tipster didn't see them sipping champagne either, but the couple certainly has plenty to celebrate. Not only did Ivanka break the news on Twitter a couple of weeks ago that Jared had proposed, late last night she sent around word that she and her dad have retaken control of Trump Entertainment Resorts, the string of casinos in Atlantic City that filed for bankruptcy protection earlier this year. Fitting they decided to eat at a restaurant with "21" in the name, don't you think?

The engagement gifts are rolling in for Observer publisher/real estate heir Jared Kushner and his newly-converted bride-to-be, Ivanka Trump. One of gifts the future Mrs. Kushner has received recently, per Urbanite: a "Swarovski crystal-studded mezuzah with leopard spots." If that's what you were thinking of getting her, too, please cross it off your list. [Urbanite]

Awww, gross again. After getting the simply nauseating news that real estate heirs Ivanka Trump and Jared Kushner are getting hitched, now we have to hear even more about it. The future Mrs. Kushner went and blabbed to Daily Intel.

Jared Kushner learns quick. And he's going to blend into the Trump family just fine. WWD reports today that the engagement ring he gave Ivanka was from Ivanka's own collection, a 5.22 cushion cut diamond that's "proprietary" to Ivanka Trump Fine Jewelry™. Ivanka will now serve as a living, breathing ad for her engagement ring line (as well as benefit from the press attention that follows). And Jared—hopefully!—managed to knock a few bucks off the price thanks to this most personal connection. Most importantly:

Awww, gross! Heiress and former Apprentice helper Ivanka Trump, 27, has gotten engaged to newspaper-destroying millionaire playboy Jared Kushner, 28. She announced it over Twitter, because that's what people do these days. But what will their parents think??

Ivanka Trump and Jared Kushner are engaged. Jared proposed last night, news that Ivanka sent out via Twitter this morning (not that it's stopping Us Weekly for taking credit for the "exclusive.") Now for the big question: Will the wedding be at the Trump International Hotel & Tower in NYC, the one in Vegas, the one in Chicago, the one that might open one day in Soho, or perhaps at one of Donald's golf resorts? At least you can rule out the Trump Taj in Atlantic City! [Gawker]

You know what people do not want to be photographed doing right now? Taking in a polo match while they sip on expensive champagne. Veuve Cliquot is sponsoring the second annual Manhattan Polo Classic this Saturday on Governors Island. The problem?

Ivana Trump and daughter Ivanka Trump recently took some time out of their busy schedules to pose for !Hola! The intimate (and very "exclusiva") portraits catch them in a few rare moments of solitude, lounging with their exotic cats and straining to express emotion. So are the creatures in this photo cougars? Leopards? Given Ivana's dating history (not to mention the title of her lightly-watched reality TV show from a few years back), we're going to assume it's the former. [Popbytes]

Graydon Carter, Robert De Niro, and Ron Perelman hosted a Vanity Fair-sponsored dinner at the State Supreme Court House last night to celebrate the opening of the Tribeca Film Festival. They were joined by Carter and De Niro's wives (Anna Scott Carter and Grace Hightower) and Tribeca Film Fest co-founders Craig Hatkoff and Jane Rosenthal, as well as a long list of guests, including Bono and Ali Hewson, Kanye West, Diane von Furstenberg, Jared Kushner and Ivanka Trump, Tory Burch and Lyor Cohen, André Leon Talley, Fran Lebowitz, Spike Lee ...
