Ariana Grande's only gone and got a tattoo memorialising fiance Pete Davidson's father, Scott, on her foot.

The singer was spotted out with Davidson sporting the numbers '8418' her left foot yesterday, the numbers being a reference to his father's badge number in the New York Fire Department. Scott Davidson died during the September 11th attacks on New York, when Pete was seven years old. The SNL star has the same numbers tattooed on his arm as well.

Needless to say, much of Twitter wasn't exactly thrilled with the concept.

Of course, this isn't the first time either of them have gotten inked up for their whirlwind relationship. Davidson previously got two tattoos after dating Grande for a few weeks, one of a bunny mask behind his ear and the pop singer's initials on his hand.

And they say love is dead in the modern world.
