They may have denied their relationship -- but they certainly can't deny these photos!

Back in 2012, Kylie Jenner and Cody Simpson denied reports that they were dating. But now old pics of the young twosome in a frisky embrace have been leaked via Twitter.

Sorry kids, you got busted!

The photos are believed to be from back when they were dating in 2012 and are thought to have been leaked by a source close to the former couple.

If these photos are old, we are a little perplexed why the pics have been leaked so long after the fact -- but maybe Kris Jenner wanted to drum up a little attention for her most forgotten about Jenner?

Back in 2011, Kylie had denied she was dating the blonde singer, "Cody and I are just good friends. That's it."

The youngest Jenner is now rumored to be dating Jaden Smith -- which she has (of course) denied on several occasions. Sounds like the lady doth protest too much!

Just yesterday we caught the Keeping with the Kardashians star hiding from photogs at LAX. Why so shy Kylie? We know you love the camera!
