Seriously? OMG! WTF?

For years, I thought that we pronounced Jake Gyllenhaal’s last name as Jill-in-hall. But then I was told it is pronounced as Gill-in-hall. So which one is it?

The actor cleared it in a promo for his appearance on Saturday Night Live this week. And it is Jill-in-hall.

However, now I am wondering if we have been pronouncing first correctly. Is it Jake or Ya-kay? What? We need to debate something about his surname since we now know how to spell it and say it.
