Baltimore rapper Caz recently went viral after a video of her at a party was posted where she delivered a very accurate impersonation of Apple’s Siri. The video caused a stir on social media, with many people saying the rapper was lip-syncing and that her impersonation was a fluke.

Now, the rapper has taken to her own Twitter account and Instagram to prove that she delivered the impersonation. Via Twitter, she said “for everyone saying that I'm faking the siri you hear in the background is me being previously recorded on someone else’s phone and my friend asked me to do it again. I’ve always had a good speaking voice it just came naturally to me one day, and I’ve been doing it ever since.

Along with that, Caz delivered a video with her in an enclosed space doing the impersonation again.
