Here's encouraging news for Kathy Freston: The hardcore vegan and dieting devotee may finally be able to let Oprah go as her most famous devotee now that it appears she may have found someone else willing to try her 21-day cleanse. Harvey Weinstein's wife, fashion designer Georgina Chapman, told a reporter at Freston's book party yesterday that she and Harvey "need to try" the cleanse. Sounds promising! And after all, it's not like diet endorsements don't run in the family! [NYO]

Kathy Freston has been popping up everywhere touting her new diet book, which is why it was hardly surprising to see she'd parked her skinny behind on the Good Morning America couch this morning. What was a little surprising? That she continues to brag about having Oprah Winfrey as a devotee, even though Oprah tried the 21-day cleanse way back in May 2008, but then went on the air to detail all the weight she'd gained just a few months later. Perhaps her supremely-connected husband could help her land a couple of new celebrity endorsements? We hear Kirstie Alley is looking to lose some weight! [ABC News]

Former MTV exec Christina Norman has been tapped by Oprah Winfrey to run her new cable network, OWN, but it turns out Norman wasn't the daytime queen's first choice. Fortune reports that honor goes to Tom Freston, who first got a call from Oprah while vacationing in Burma in 2006 but turned down offers to run both Harpo and OWN. No matter. Oprah has since hired Tom as a consultant since he happens to be her "business soul mate." Nice to know the fact that Kathy Freston's 21-day "cleansing diet" didn't end up doing Oprah much good hasn't diminished her opinion of the Frestons! [Fortune]

Model-turned "wellness expert" and "spiritual counselor" Kathy Freston credits yoga and veganism with helping her gain self confidence, quit smoking, and find her soulmate—who just so happens to be exceedingly rich former CEO of Viacom, Tom Freston. She's been peddling her self-help books to socialites on the Upper East Side for years, although she now appears to have bagged her biggest convert yet—Oprah! The daytime queen is on week two of Freston's 21-day cleanse, and she even started a blog about her experience. No meat, no sugar, no gluten, no alcohol, no caffeine—21 days has probably never seemed so long. A video of Oprah admiring a falafel ball after the jump.
