Beyonce Says 'I Want to Have More' Kids, Will Give Blue Ivy a Sibling

,All though you wouldn't be able to tell from looking at photos of Beyonce in a see-through feathery number at Monday night's (May 7) Met Gala, the singer just had a baby four months ago! While walking the event's red carpet, the singer stopped to talk to ET about her family -- and whether or not she and hubby Jay-Z plan on expanding it.

When asked if she wanted to give baby Blue Ivy a sibling, Bey answered without hesitation, "Of course. Yes!" The glowing new mom continued, "I don't know how many. God knows. I don't know yet, but I definitely want to have more."

So does Bey have plans to start on baby #2 in the near future? "Ahh ... I don't know about soon," answered the new mom. Then, naturally, the conversation turned to the subject of Beyonce's impossibly slim post-pregnancy body. According to Queen B, she's just been, "Working hard. Working so hard. There are no secrets." Just good, old fashioned "discipline!"
