Awwwwww, more sisterly love from Jessica and Krystal!

Krystal was born on October 24, 1994, making her 22 now!  To celebrate, Jessica posted a cute picture of the two and wrote sweetly, "Don't grow up too fast! #happybirthdaybabykrys #loveyoumore #161024."

Can they seriously be more sister goals??  Happy birthday, Krystal!
