Shiloh: OK Cover Girl

Brad and Angelina's 2-year old daughter Shiloh is getting ready to be a big sister. She is finally coming around to accepting that she's going to be a sister and it's a big relief in the Jolie-Pitt household.
"It took her a while, but now she's as excited as the rest of the family," a Jolie-Pitt insider tells OK!. "She puts her hands on Angie's stomach to feel the twins kick and she jumps back and starts grinning!"
Shiloh has begun sleeping in a big-girl bed and is even almost potty trained.
"She's got her pull-up diapers and tells Mom and Dad when she has to go to the bathroom," a source tells OK!. "She's trying to get the hang of it all on her own — just like she did with walking."
