Rihanna and her halftime show team was "very careful" not to reveal she was pregnant before the Super Bowl last weekend, the director of the show said this week.
"She was very careful about who knew," Hamish Hamilton, who has directed the halftime show since 2010, told "Entertainment Tonight." "And we only knew, really, at the very latest stages. Her and her team carefully managed that, and we obviously also then carefully managed that."
The "Rude Boy" singer became the first pregnant woman to headline a halftime show when she appeared on a platform more than 60 feet above the field on Sunday cradling her baby bump.
"It's a very, very personal, joyous moment," Hamilton said of her pregnancy. "So, it's for her to tell the world, you know? So, not only were we obviously very mindful of the fact that she was pregnant, but we're also very mindful of this kind of a show hasn't been done before either."

Hamilton called the show "ambitious" technically, adding that the production team had a "huge amount of respect for the endeavor that we were taking on."
"I think, given the ambition of the idea, the kind of lunacy, almost, in some ways, of the idea, I think anybody who was going to kind of tell the world was like, 'You know what? Let me keep the secret,’" he added.
He said keeping Rihanna and the other performers safe during the high-flying show was their top priority.

"There were never any times when we were putting anybody in danger, but there were a lot of times when we needed to stop, evaluate the safety and then carry on," he said.
He said the technical aspects would be ambitious in a Broadway show "where you've got months and months to set it up ... [but] this is a Super Bowl. I mean, you've got eight minutes to get all that stuff out. Check it, safety check it, make sure it's cool, deploy it, and then fly her up. It was ridiculously ambitious."
