Pouring My Morning Coffee...

I have had the same nagging question in my head every morning for quite some time now when I pour myself a cup of coffee...

Does the coffee stay hotter if you:

Pour a little milk at the bottom of the cup and then pour the hot coffee in...

OR

Pour the coffee into the mug and then pour in a little milk...

My hypothesis is as follows:  The coffee stays hotter if you pour the coffee in first and then the cold milk. 

What say you?
