Rachel Bilson and a female friend stepped out for a stroll around Los Feliz on Monday, and the Hart of Dixie star got some hands-on mommy experience as she toted her pal's little bundle of joy. Aww how cute!

The 30-year-old former OC actress and her beau have been on and off for years, but with all the recent spottings of them together, we have to wonder... is the adorable duo prepping for parenthood?

We hope so! Talk about the world's most genetically blessed baby!
