The twins' arrival came earlier than expected. Angelina Jolie's departure won't be following suit.

A spokeswoman for Lenval hospital, where the Jolie-Pitt brood welcomed new additions Knox Leon and Vivienne Marcheline, told E! News that the new mother remains in the maternity ward at the hospital and will not, per the latest round of speculation, be checking out today.

"After a C-section, the normal stay for a mother in the Lenval hospital is between eight and 10 days," Nadine Bauer said.

When asked directly if Jolie was due for discharge later today, Bauer said, "No."

"And I'm not sure what day she will be leaving. Only when Dr. Sussmann is completely satisfied that she is in good health and fully recovered from the C-section."

Jolie and Brad Pitt welcomed the twins last Saturday, meaning while Jolie isn't packing her bags just yet, she could theoretically be released from the hospital as early as this weekend—a possibility that's not lost on the increasing scrum of media assembled outside the facility.

But a hospital source told E! News that standard procedure may not be the only reason Jolie is being kept under Sussmann's watch, claiming that the good doctor is hoping to keep Jolie in the hospital until she is fully recovered as she will likely take on too many responsibilities—and not enough bed rest—if left to her own devices.

"Angelina has four young and lively children at home, and he suspects the temptation to get up out of bed and play with them will overwhelm her," the source said.

"He knows how much she misses the other children, but he feels that she will benefit from a few extra days' rest. They're being very well cared for."

And not just by Pitt.

Earlier this morning, Jolie's brother, James Haven, paid a visit to his sister, leaving around 10 local time.
