Julia Roberts: Oct. 28
There are a handful of stars who might have found the fountain of youth, and the same can be said for this new group of stars who turned 50 this year. Couples like Faith Hill and Tim McGraw and Keith Urban and Nicole Kidman all hit the half-century mark, along with comedians Leslie Jones and Will Ferrell. Also in the mix were Vin Diesel, Jimmy Kimmel, and Julia Roberts. It's hard to believe, but there's only one possible explanation: they must be vampires.
