Prom is a huge moment in many teenagers' lives. It can truly be a whirlwind of emotions leading up to the big dance. Who's going to ask you as their date? What are you going to wear? Will someone have the same dress as you? Will your mom embarrass you in front of all the other parents when you're taking pictures? (Probably.) Where's the after party? Are Tammy and Joey going together even though they broke up?

It's somewhat comforting to know that even the most famous of pop stars like Bruno Mars, Adam Levine and Demi Lovato all experienced the broad range of emotions that come with attending a high school prom. Just think, Usher had to work up the courage to ask a date to prom. Usher! One of the sexiest men to ever walk the planet! And beauties like Britney Spears have to wonder whether they'll look good enough for their date, something that seems absolutely laughable now.

So, strap on your dancing shoes, fasten your corsages and boutonnieres, and grab your date as we look back on these celebrity prom pictures!
