Your first warning sign was probably the description of the explicit photo as "going around the Internet." You see that phrase, and you should put your bullshit detectors on. But Diggins herself took to Twitter to squash those rumors once and for all.
"Gotta clear this up. I dnt knw wht pic is going around, but tht is NOT ME. Idk who is going around trying to defame my character, but it's sad
"The people that know me and love me know that I would never handle myself in such a careless and classless manner.
"I can truly say I am hurt by this...I dnt believe how someone could attempt to ruin my name but being untrue. I am stronger than this though
"I will not run away and hide. There is no reason to.....goodnight and I will be back to continue my thoughts and tweet regularly tomorrow..."
Even Notre Dame, which is having a hell of a PR day, put out a statement, saying "The online photos purportedly of Skylar Diggins are not authentic, and the University is providing her with all possible support in dealing with this defamation. The University's General Counsel has demanded that those responsible for posting this reprehensible material immediately remove it."
Sorry, creepers. You'll have to make do with athlete dong shots.
