A trio of THG favorites, all famous for very different reasons, celebrate a birthday today.
First, Mad Men star and Saturday Night Live host extraordinaire, Jon Hamm, turns the big 4-0. Does it get any cooler, funnier and more talented than this TV icon?
Next, House actress Olivia Wilde is now 27, as she's seen her career take off over the past year with a steady role on that Fox hit, along with lead in the sequel to Tron. We like when she poses naked.
Finally, Carrie Underwood, the most successful American Idol champion in history and a natural beauty, hits the age of 28. Send in your birthday wishes to these three stalwarts now!
