First Lady Michelle Obama celebrates her 48th birthday today. Michelle remains incredibly youthful and fit, especially by First Lady standards. If she worked in Hollywood, she’d probably have us all convinced she’s in her mid-thirties.

While her husband’s approval ratings have fluctuated dramatically during his years in the White House, most of the country still seems to love Michelle. And why wouldn’t they? Her commitment to charity work and nationwide physical fitness have made her one of the most highly-visible and proactive first ladies in recent memory. On top of that, she frequently manages to look fierce at public events, and her fashion sense has made her an international style icon. But in case you were worried that Michelle’s ego has grown along with her public profile, bear in mind that the busy mother of two still shops at Target.

Michelle and her family have a tough year ahead of them, as President Barack Obama will mount a campaign to maintain control of the White House in the face of stiff competition. Being a politician’s wife during election season can be a strenuous ordeal, but Michelle certainly seems up to the challenge.
