Turns out Reese Witherspoon is 63% Irish.

WTF would her family lie about their Irish heritage and pretend to be Welsh/Scottish?!

I always get the impression a lot of celebrities lie about stuff like this.

I mean Irish people average 7 or 8 babies per family.

Do the math.

I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
