Demi Lovato is a wonderful big sister–at least according to little sister, 13-year-old Madison De La Garza. During a recent interview with Seventeen magazine, Madison sang her sister’s praises, but admitted it was tough dealing with Demi Lovato constantly being away.

“I think when people say they wish Demi Lovato was their sister, they don’t realize how hard it is to be related to someone who’s constantly away on tour. But she’s good at making time for me,” she explains.

“We text constantly, and whenever she sees a funny tweet, she’ll screenshot it and send it to our family group message (which includes our mom and our sister, Dallas). My phone is constantly going off just from that. When Demi is home, our relationship is just like any sisters’. We get fro-yo and watch the ID channel–we’re obsessed–and we talk about anything and everything. I know I can trust her with it all,” Madison adds.

Demi Lovato isn’t the only member of her family in show business either. Madison De La Garza played the role of Eva Longoria’s daughter on the hit TV show Desperate Housewives.

Fiercely protective of her sister, Demi Lovato came to her defense last year during a bullying situation.

“Last year I got a ton of negative comments after I posted a Vine on Twitter where I was cooking with Demi. People made fun of me, saying I had a hunchback,” De La Garza revealed. “Demi freaked and direct-messaged people to yell at them, and she tweeted at her followers to stand up for me. Sometimes I wish she wouldn’t give people attention – I’ve learned not to – but when people hate on me, she can’t really hold back. She’s strong and she’s a free spirit, and that’s what I love about her.”

Demi Lovato encourages Madison to call her often.

“I want her to come to me with things. I just let her know that I’m always there for her, whether I’m on the other side of the world or I’m next door,” she says.

Just imagine how cool it must be for Madison De La Garza to tell people her sister is the “Cool for the Summer” singer. Demi Lovato is no doubt proud of Madison, too. How do you suppose Madison and Demi’s boyfriend Wilmer Valderrama get along?

It’s nice that Madison has an older sister like Demi that she can turn to when she needs advice. Demi Lovato has been through a lot. She can surely share some of her experience with her little sister.
