It’s Hilary Duff!
The 25-year-old singer — and former Lizzie McGuire star, of course — tweeted this precious flashback photo on November 1. Hilary gave birth to her first child, son Luca Cruz Comrie, with husband Mike Comrie, back in March. She tweets plenty of photos of the adorable tyke, and now we have a picture of his mommy back in the day, too. What do you think: Can you spot the family resemblance?
