Ivanka Trump is no longer just a real estate executive, jewelry designer, proponent of "fresh-tasting, healthy" microwaveable meals, and real estate heiress about to settle down with a real estate heir. She's now a published author, too! Ivanka's motivational book, The Trump Card: Playing to Win in Work and Life, is now here (with a blurb by her almost-boss Anna Wintour, no less), and last night she celebrated its publication with a party at—where else?—Trump Tower. Naturally, all the Trumps turned out for the fête. But while papa Trump wasn't necessarily in tip-top shape (he's "put on a bit of weight around the middle," reports David Patrick Columbia), Ivanka was "radiant and remarkably composed," reports Vanity Fair, even though she's getting married in a mere 10 days. Her advice to other women who might have to juggle a wedding merging two billionaire families while also promoting a soon-to-be bestseller at the same time: "Be relaxed, try to enjoy the moment, and remember: it's just a great party!"
