The fan joked that it was her "long-lost twin sister, Poot," who had been "locked in a basement her whole life."It is worth noting that at that time, Demi Lovato was not okay with it. In a now-deleted post from that year, she expressed frustration at the joke. However, in a 2023 interview with Harper's Bazaar, she revealed:"When Poot went viral, that actually sucked because I thought that was a real picture of me. Later, I felt better about it because I realized that was not my face."Demi Lovato included a brief shot of Poot in her "Fast" music video. She also had a Poot-themed cake for her 31st birthday in 2023. "Fast" is the lead single of her latest album, It's Not That Deep. She will kick off a tour in 2026 to support the record.
