Does Mitt Romney use spray tan? It's the question we've all asked, and answered, with, yes, duh, of course, look at this picture. But in the absence of sources, we've been stuck just pointing at this photo, in which Mitt Romney is clearly wearing spray tan.

Until now! Buzzfeed's McKay Coppin's gets a "knowledgeable source" to dish:

A knowledgeable source tells BuzzFeed the answer is in a bit of cosmetic technology used commonly by celebrities: spray tanning. The Republican nominee has made a habit of spray tanning before major speeches, debates, interviews, and other events that have a chance of getting wide TV coverage, the source said. He pays for the process out of pocket - sparing his campaign the expense, and the task of masking it on public campaign finance reports - and steers clear of public salons where he could be recognized. Instead, he gets misted down in the comfort of his own home or hotel suite.

The Romney campaign flatly denied that the candidate spray tans: "Not true," spokeswoman Andrea Saul said in response to an inquiry.

What else do you need to know?
