Good thing it didn't happen!

Beyonce and husband Jay-Z worried that daughter Blue Ivy would "feel left out" after twins Rumi and Sir were born, but the 5-year-old has welcomed them with open arms and they have an unbelievable bond, People reports.

"Beyoncé has been very busy with the newborns, but she’s also been able to relax a bit. It’s helped her that Blue has been such an amazing big sister. There was no need to worry because Blue is great. She takes her job as a big sister very seriously and helps out a lot," a source dished to the mag.

The eldest of the Carter clan is ready to have a little independence, though.

"Blue is excited about starting kindergarten. She misses her friends. It will be fun for her to get back to her own life at school. Beyoncé is excited for her too but keeps saying that she can’t believe Blue is starting kindergarten. She thinks Blue is growing up way too fast!” the source added.
