One of the larger-than-life moments of the 25th season of The Oprah Show came when the reunited Backstreet Boys serenaded Noelle and Meghan, two of the boy band's biggest fans, as they stepped off a plane at O'Hare Airport.

Producer Leslie Grisanti's team—including senior associate producer Erinn McNeill and senior production assistant Gwen Martin—needed some help to pull off this stunt. Because the Backstreet Boys and Noelle and Meghan landed at around the same time, the producers had to scramble to make sure the surprise was flawless. "The timing was perfect, but Gwen really orchestrated all the logistics there on the ground," Leslie says.
