Photos: Kate Middleton looks so good at first post-baby event

Looks like this new mom is bouncing back after giving birth with no problem!

A stunning Kate Middleton attended her first official post-baby event, accompanying her husband, Prince William, on Friday to the Ring O'Fire Ultra Marathon in Wales.

The beaming Duchess of Cambridge stepped out in black skinny jeans, a patterned blouse, and green blazer. Middleton's svelte figure is reportedly not the result of dieting though she had her baby just five weeks ago.

No word yet on what the Duchess was wearing exactly, but that information will come. And then the items will sell out.
