Where did the time go? Maddie De La Garza recently celebrated her Sweet Sixteen (yes, she’s no longer the adorable child star of Desperate Housewives fame) — and the beautiful teen is the spitting image of her older sister Demi Lovato. Maddie wore a long white romper with removable skirt and tiara as she celebrated her birthday a little bit earlier with friends.

“Love these boys,” she captioned an Instagram post from her big — and it didn’t take long for her fans to bring up the resemblance with the “Sorry Not Sorry” singer. “Omg! I remember when I started being a Lovatic you were just 5 years old. You’ve grown into such a beautiful woman,” one commenter wrote. Another added, “Can’t believe ‘Demi’s baby sister’ is so grown up already.” Watch the video below to see her today!

Demi also took to Snapchat to share some selfies and even record a duet of her new song with Luis Fonsi with her little sister. Their dad even makes a cameo on the dance floor. We love seeing these siblings together — and they clearly have a close bond despite their nine-year age gap. Demi recently admitted her little sister was the main reason she went to rehab.

“There were a few [interventions], but the final one, everyone was like, ‘We are no longer going to leave, we aren’t leaving,’” the 25-year-old said on The Jonathan Ross Show. “That was the moment when I thought, ‘OK, I really need to get help and get sober.’”

She continued, “I knew that I had a lot of life ahead of me, but one of the main reasons of getting sober was so that I could be around my little sister because my mom and dad [said I couldn’t be around her] if I was doing stuff.” We need a Demi and Maddie collaboration ASAP!
