Why Does Rachel Bilson Keep Practicing Being A Mommy?

Is there something you’re not telling us, Ray-Ray?
Last week, we caught Rachel Bilson playing make-believe Mommy in Los Feliz.
On Sunday, she was spotted home improving with boy-toy Hayden Christensen!
And now she’s acting like an overprotective Mama Bear coming out of Nat’s Early Bite, making sure half-sisters Rosemary and Hattie hold her hand and look both ways!
It almost sounds like she’s practicing for Motherhood!!
Is Darth Vader prepping his, uhhhh, Death Star, to give you some teeny-tiny Skywalkers?? Were you two picking out paint colors for the baby’s room?
You can confide in us, Rachel!!
We PROMISE it’ll stay our little secret, LOLz!!
