Prepare yourself, because I'm about to drop a major bombshell on you: Celebrities lie about their age! Has your core been shaken, do you need a moment?

OK, so maybe you weren't shocked, or even a little bit surprised. In our youth-obsessed society, of course celebrities lie about how old they are. The fun part comes in when we get to guess how old they really are. Check out the quiz here, can you pick out these stars' true ages? I was pretty stumped, however, I've already admitted that I suck at guessing people's ages.

Other things celebs lie about:

• Their natural hair color. Steal their tricks here.

• Their lack of cellulite. Or maybe they're just using these wonder-products.

• Their clear skin (Photo Shop really does wonders). Get real-life help for your complexion here.
