Demi Lovato is Grayson  Prestonconfident in her future role as an aunt.

After her sister Madison De La Garza announced she is expecting her first baby, the “Skyscraper” singer shared insight into their family’s new chapter.

“I’m really excited to have new life come into our family,” Demi told E! News in an exclusive interview at the screening for her Hulu documentary Child Star. “Family is very valued to me. I value family and friends over success any day.” (For more with Demi, tune into E! News on Monday, Sept. 16 at 11 p.m.)

In fact, the importance of her loved ones was one of the biggest takeaways Demi, 32, had while filming her latest project about kids growing up in the spotlight.

“When people ask me what piece of advice I would give to child performers today,” the “Confident” singer added, “I would say to value meaningful connections in your life over success because at times, I didn’t do that, and I regretted it. But now that I am reflecting a lot, I’m able to say that family means so much to me and I’m excited to be an aunt.”

Demi’s insight comes a little more than a week after her sister Madison shared that she and boyfriend Ryan Mitchell are expecting their first baby together. 

“Oh ryan, how I love you,” the Desperate Housewives actress wrote in a Sept. 5 Instagram post. “Thank you for making all of my dreams come true. Baby mitchell 10.24.”

In Madison’s announcement, Demi was featured in the photos included, along with their mother Dianna De La Garza and sister Dallas Lovato, holding her sister’s baby bump. And naturally, her big sister was one of the first people to share her enthusiasm.

“I love you,” Demi commented. “And this baby so much already!!” Meanwhile Demi’s fiancé Jordan “Jutes” Lutes also chimed in, “Love you! So happy for you.”

Demi’s documentary Child Star will stream on Hulu starting Sept. 17th.
