Skinny mini! It's been 10 months since Rachel Bilson gave birth to her little Disney princess, Briar Rose Christensen, but the Hart of Dixie alum's post-baby body is already slimmer than ever.

Taking to Instagram on Monday, Sept. 14, Bilson, 34, shared an "outfit of the day" photo, which showcased her polka-dotted tee and denim skirt combo, not to mention her trim figure. She captioned the snap simply, "Monday."

Bilson shared another peek into her closet—or rather, jewelry box—the day before, too. Then, the O.C. actress, who shares Briar Rose with her fiancé, Hayden Christensen, offered fans a close-up shot of an adorable bauble—a little gold Catbird ring, topped by the letters "BR," presumably in honor of her little girl. To caption the sweet shot, she added an arrow-through-the-heart emoji.

Recently dishing on Briar's princess-perfect name on The Hallmark Channel's Hope & Family, Christensen, 34, said, "There's a Disney reference there I suppose. The original Sleeping Beauty is called Briar Rose. Rachel—we both love Disney—but Rachel especially was very keen on the name."

The proud pop added, "We have Disney songs playing around the house 24/7!"
