Rodriguez Aug. 20 marked Demi Lovato's 26th birthday, and her 16-year-old sister, Madison De La Garza, made sure to honour Demi on her special day. Along with a childhood photo of the pair, Madison shared an emotional post, thanking God, Demi's team, and her fans for all of their support following Demi's reported drug overdose last month. "Today could have been one of the worst days of my life . . . without all of these people I wouldn't have my big sister anymore," she wrote. Madison also shared some of her favourite memories with Demi, adding, "I wish that everyone could see the silly little things that she does, like how her nostrils move when she says certain words and when she brushes my hair behind my ear when I'm trying to sleep." Demi was hospitalized on July 24 after she was found unconscious at her LA home due to an apparent drug overdose. Demi is currently receiving treatment at a rehab facility and shared a message for her fans on Instagram earlier this month. "I will keep fighting," she wrote. Take a look at some of Demi and Madison's sweetest sisterly moments ahead. today could have been one of the worst days of my life, but instead i get to spend it thanking God, the incredible doctors, demi's team, and everyone across the world who offered their support - without all of these people i wouldn't have my big sister anymore. i've been thinking about how i wish that everyone could see the silly little things that she does, like how her nostrils move when she says certain words and when she brushes my hair behind my ear when i'm trying to sleep, because those are the things i'm thankful for today. they seem so small, but those little things make up my sister - not a singer, not a celebrity, and definitely not what she's been described as in the media - she's a daughter, a friend, and my big sister... and i am so, so thankful that i can tell her happy birthday. #happybirthdaydemi ❤️ A post shared by Madison De La Garza (@maddelagarza) on Aug 20, 2018 at 10:34am PDT 1 / 10 Image Source: Getty / Kevin Winter 2 / 10 Image Source: Getty / Jason LaVeris 3 / 10 Image Source: Getty / Mark Sullivan 4 / 10 Image Source: Getty / Gregg DeGuire 5 / 10 Image Source: Getty / George Pimentel 6 / 10 Image Source: Getty / Michael Buckner 7 / 10 Image Source: Getty / Alberto E.
