Demi Lovato’s younger sister, Madison De La Garza, celebrates a very personal milestone. On TikTok, the 21-year-old ‘Desperate Housewives’ actress reveals she’s gone 230 days ‘without using.’ While Madison did not specify what she has stopped using, she previously posted a video in late January which featured a filter that read, ‘I’m quitting [leaves emoji] in 7 seconds.’ The emoji has been known to refer to marijuana on social media.
