Kristen Bell has a lot to celebrate this week.
In addition to being an admitted lover of the holiday season (she stars in Frozen, how could she not?), she's also ringing in her 3-year-old daughter Delta's December birthday in the sweetest way.
Bell shared four photos of herself on Instagram on Tuesday night where she is heavily pregnant and, in some cases, wearing mesh pregnancy panties.
"Three years ago today. 47lbs heavier. Getting through painful contractions with backrubs and breathing. Occasionally swinging from the IV pole to try and feel sexy and open up my hips," she wrote. "After 36 hours of labor I met a girl i love more than all the molecules in all the world. Happy birthday, Delta. Love, mom #meshpanties."
In the accompanying photos, Bell is shown straddling a balance ball with an enormous baby bump, posing alongside her husband Dax Shepard, swinging from an IV in a hospital gown, and looking content while cradling baby Delta.
We wish Delta the happiest birthday!
