Haters gonna hate, and the Pres is gonna Pres.

Taylor Swift really has conquered the world in the last year, making fans (and friends) out of some of the biggest names in the world. And you can now add Barack Obama to the list of people who get down to this sick beat (even if he's not really singing it).

The latest BarakDubs tackles Swift's earworm tune of 2014 and even though he's not singing it properly here, you just know he has mumbled and hummed this to himself at least once.

The amount of times that Obama has 'Mmm-hmm'-ed on camera is staggering.
