When Big Sean posted a selfie to his Instagram account earlier this week, it was his caption — not the photo — that got everyone talking!

After writing, "I give her that D… #Detroit" on April 14, fans immediately speculated the pic was intended for girlfriend Ariana Grande and that "D" didn't actually stand for Detroit (if you catch our drift). Needless to say, the rumors caught the attention of the pop diva's father, Edward Butera.

Commenting on the image, Butera pulled a total dad move and wrote, "that D. better be Detroit Sean."

The rapper has yet to respond to the comment, but we have no doubt that he's planning his next move VERY carefully. It's never a good idea to piss off pops!
