Happy 37th birthday to the lovely and talented Danielle Panabaker! It's hard to believe our favorite Powerpuff Girl is all grown up. You have come a long way from being a teenage heartthrob in "Sky High" to a genius scientist in "The Flash." Cheers to another year of slaying on screen and aging like the finest wine. May this birthday be filled with lots of laughter, love, and all the cake you can eat. Here's to many more years of spreading your sunshine and making us all swoon. Happy birthday, Danielle! P.S. Can you please share the secret to eternal youth?
