I've never watched NASCAR but don't they say, "start your engines?"  Well, it's time to "start your brains!"  Let's get you guys thinking this morning with another Tuesday Morning Brain Teaser.

How many times have you gotten the question, "how old do I look?"  I hate that question, and I never come close.  How good are you guys at guessing someone's age?  Today's brain teaser is called 'Who's Older.'  I'm gonna give you different pairs of celebrities and you have to guess which one is older.

Here we go:

1)  Britney or Christina?

2)  Madonna or Cyndi Lauper?

3)  Jennifer Lopez or Jennifer Garner?

4)  Matt Damon or Ben Affleck?

Good Luck!
