Today is all about Rachael's new book, Rachael Ray 50! Up first, the man who gave Rachael her big break in TV, Al Roker, is here — and he's interviewing Rach about some of her personal stories in the book. Plus, we've got special messages for Rach all hour long from celebrity friends, including one from Michelle Obama. In the kitchen, Rach is making one of the 125 recipes from the book — a Carbonara dish!

Rachael's husband, John, joins her in the kitchen today, and they're chatting with their pal Al Roker, who shares wisdom from his new book. Plus, Rach is making an end-of-summer pasta with sweet corn and zucchini, and John mixes up a fall-inspired cocktail.
