February 1st seemed to be chock-full of celebrity birthdays from Lauren Conrad (who turns 25 today) to "Glee" star Heather Morris, who turns 24. The actress-singer-dancer got plenty of birthday wishes from her "Glee"-mates, including Naya Rivera who shared, "Happy birthday Heather Morris!! On my my to work to tell her in person!" But, Ashley Fink (a.k.a. Lauren Zizes) had a different kind of gift for Heather (pictured), as she tweeted,"#HappyBirthdayHemo I love that Heather Morris. I'm gonna kiss her face!"
Elsewhere, Rachelle Lefevre may not be appearing in the final chapters of "The Twilight Saga," but that doesn't mean the actress (who celebrates her 32nd b-day today) isn't still part of the family. That was evident as some of her former co-stars took to their Twitter pages to send Rachelle birthday wishes, including Edi Gathegi, who wrote, "Happy Birthday to my sweet sweet @RachelleLefevre i hope today is splendiferously phantasmagoric."
