Here’s to another year of amazing looks for January Jones. The X-Men: First Class actress is celebrating her 38th birthday today, but it’s clear to see that she just doesn’t age.

We were first introduced to Jones back in the early aughts, when her career began to flourish as an actress—and as an Abercrombie & Fitch model. But her transformation gallery proves that she was a beauty long before she became a household name.

From her high school days working at the local Dairy Queen in Sioux Falls, South Dakota, to her show stopping role on the breakout series Mad Men, Jones has always possessed undeniable star power—and the proof is in the pictures. Celebrate the Hollywood bombshell’s special day by taking a look at her evolution in our gallery here.
