Now that E! News is reporting that Blue Ivy Carter is about to be a big sister, I guess we can figure out what kept Beyoncé from performing the other night.

In her first appearance since that cancellation, the singer apologized to fans in Antwerp, Belgium for not being able to go on with her show the night prior due to dehydration and exhaustion (and morning sickness and other pregnant lady stuff).

A still audibly ill Beyoncé thanked her fans for all their love and support. She also reminded fans that she was back on stage against doctor’s others.

Beyoncé said:

“I just want to say I feel so good to be on the stage. I have the best fans in the world. Now my doctors told me not to perform tonight, but there was no way in the world. I just have to say that ya’ll give me so much inspiration, and I just want to thank you guys.”

After that, she went into a performance of “Flaws And All.”

“This song is for all for you, BeyHive. I love ya’ll,” Beyoncé said.
