Emily Deschanel, better known as Dr. Temperance "Bones" Brennan, is turning 40 today! The Bones actress is ringing in her special day today, and we're sure said celebrations will include younger sister, Zooey Deschanel, 36.

These two might differ in both style and TV personalities—Zooey plays quirky, yet awkward, Jessica Day on New Girl—but they're sisters through and through. Not only do they film their TV shows on the same FOX lot, they both gave birth to their respective babies just a few months apart!

In June 2015, Emily welcomed her second son with husband David Hornsby, while Zooey simultaneously married fiancé Jacob Pechenik, and gave birth to their first child (a girl!) just a month later. Talk about being close siblings!

If anything, their adorable demeanor on the red carpet says enough about their sisterly bond.
