Since the news of Hilary Duff's pregnancy hit, Hilary has been a trending topic on Twitter. It seems that most people were caught off-guard, and the news makes them feel old.
@safertohateyou recalled Hilary's Lizzie McGuire days:
It's odd to think Hilary Duff is pregnant. It seems like yesterday when she was in love with Ethan and hanging out with Miranda and Gordo.
Hilary Duff is going to make the cutest hockey mom. #jealous
And finally, hundreds of people have tweeted a variation of this theme lamenting that their childhood is now officially over:
Hilary Duff is pregnant. Harry Potter is over. Zack & Cody graduated. Hannah Montana revealed her secret. #childhoodover
