Fat’s not all, folks — the night before Paula Deen went on “Today” to announce she’d been diagnosed with diabetes and was converting to healthier eating, she was scarfing down lamb chops and tiramisu at the posh Asellina restaurant on Park Avenue South. Deen, who’d gone to the eatery with a large group, polished off the entire dessert, and told the wait staff it was “the best tiramisu she’d ever tasted.” The next morning, the butter-loving chef was dishing about how she’d been diagnosed with the disease three years ago, and revealing she’d signed a lucrative endorsement deal with diabetes drugmaker Novo Nordisk.
