As he played the piano, Ehrich's face suddenly betrayed that an "uh-oh" moment was coming. He whispered, "I'm on Live!" as a makeup-free Demi stepped into frame. "Hm?" she asked, to which he again whispered, "I'm on Live!"
Getting the picture, Lovato burst into laughter and covered her face, while Ehrich broke into a grin and covered his mouth in shock.
Us Weekly had already confirmed that Lovato, 27, and Ehrich, 28, were an item, and have been dating since some time after her holiday split with Austin Wilson.
The Instagram Live relationship reveal may truly be a case of "Sorry Not Sorry"!
