Demi Lovato is standing up for extraterrestrials. The 29-year-old singer is revealing why they don’t use the word “alien” when referring to extraterrestrial beings. “I think that we have to stop calling them aliens because aliens is a derogatory term for anything. That’s why I like to call them ETs!” they told Pedestrian TV. The “Cool For The Summer” singer just released their four-part Peacock series “Unidentified with Demi Lovato” which follows Demi, their best friend Matthew Scott Montgomery and Demi’s sister Dallas Lovato, as they search for the truth regarding extraterrestrial life.
