Memo Pad: Discussions... Cover Girl... Bumping Up...

LEADING THE DISCUSSIONS: While CNN anchor Anderson Cooper was a logical choice to moderate the YouTube-CNN presidential debate on Monday, the Rupert Murdoch-owned MySpace may choose more unconventional hosts to lead its Town Hall discussions with 2008 candidates. Sources say Ivanka Trump is being courted to serve as one of the moderators for the dozen or so upcoming MySpace discussions to be held at college campuses across the country. Wendi Deng, wife of Murdoch, the founder and chief executive of News Corp., suggested the idea to Trump, believing the real estate mogul and occasional columnist for lad mag Stuff would be a great representative of the young, educated and upwardly mobile voting population, a source close to News Corp. said.

Beginning in September, MySpace will host a series of hour-long conversations during which one presidential candidate will field questions sent by viewers at home via the site's instant messenger service. The talks will be broadcast live via the site. Participants will include Sam Brownback, Hillary Clinton, John Edwards, Rudy Giuliani, Duncan Hunter, John McCain, Barack Obama, Mitt Romney and Tommy Thompson. Sources say it has not yet been decided whether the broadcast also will appear on Fox News. Trump and a MySpace spokeswoman declined to comment. — Stephanie D. Smith

COVER GIRL: In August, Jennifer Lopez landed the cover of Glamour, but come September, her face will be attached to 16 different Conde Nast titles. The actress is the cover girl for Fashion Rocks, the outsert that will be attached to Glamour, Vogue, W, Allure, Self, Teen Vogue, GQ, Details, Men's Vogue, Architectural Digest, Lucky, Domino, Vanity Fair, Conde Nast Traveler, Wired and The New Yorker. The magazine promises "models on nearly every page" and articles on artists such as Amy Winehouse, Carrie Underwood and Sean Lennon. A spokeswoman said ad pages will range from 75 to 100 in each issue, which is 15 percent more than last year. All will be revealed on Friday, when magazines start hitting subscribers' mailboxes. — Amy Wicks

BUMPING UP: Marie Claire editor in chief Joanna Coles has replaced outgoing senior fashion editor Eric Nicholson by promoting fashion editor Zanna Roberts. Roberts joined the magazine in October, but before that served for seven years at the title's British edition, most recently as beauty and style editor. She also was responsible for tapping Helena Christensen to shoot photographs of supermodels which appeared in a photo feature in the August issue, and at the charity event Marie Claire held last week at Milk Gallery in New York. Apparently Coles, a British transplant, appreciates those with similar roots — in May, Coles hired Suzanne Sykes as creative director to replace Paul Martinez. Sykes most recently served as art director for Britain's weekly Grazia, and helped launch the British edition of Marie Claire. — S.D.S.
