Today is the birthday of Helen Slater, famous around these parts for playing Kara in Supergirl, as well as Lara on Smallville and Eliza Danvers on the CW show Supergirl. She also starred in The Legend of Billy Jean, City Slickers, Ruthless People, The Secret of My Success, and has appeared in numerous shows, including the final episodes of Mad Men. In addition, she loaned her voice to DC Superhero Girls as Martha Kent and Batman: The Animated Series as Talia al Ghul.
If you didn't know, she's also cut a few records (she's pretty great!), and continues on her trend of being terribly crush-worthy.
