Jady Duarte posted pics on WhatsApp in which the world class athlete is shirtless, cuddling with her in bed, and kissing her neck.
You can check out the damning photographic evidence (below):
That's gotta be rough for poor Kasi, especially considering the 30-year-old refers to his longtime love as the "First Lady" to his "President," like in the caption for this Instagram photo they took together (above).
But apparently the affair going public isn't only painful for the runner's GF. His one night stand also claims to Brazilian paper Extra that she's incredibly embarrassed that the pics got out, saying:
"It's very negative. I never wanted to be famous, I'm dying of shame."
Well… considering she's the one who shared the photos with friends, we aren't entirely sure what she expected to happen.
