According to AP, the singer opened up about it at a live interview last night for her DVD screening of "Live from Roseland," in New York City.
"The whole time I definitely was thinking, `Everyone knows, everyone can see.' When you're pregnant, it's a little bit harder to breathe, so it was hard doing all the choreography and singing at the same time."
