Selena Gomez couldn’t help but praise her friend, Demi Lovato, following the release of the latter’s YouTube documentary, “Simply Complicated.”

Lovato shared a clip from “Simply Complicated” via her Instagram account on Oct. 17. One day later, Gomez commented on her post and called her project “beautiful.” She also said that she’s happy for her “Barney & Friends” co-star because she is always real and bold. “I wish more people were like you.” In a follow up comment, Gomez wrote, “Love you.”

Since starring in the hit TV show, Gomez and Lovato have gone on their separate ways to stardom. In 2007, the “Sorry Not Sorry” singer starred in “Camp Rock,” while the “Kill Em with Kindness” singer starred in “Wizards of Waverly Place.” Around the same time, they also starred in multiple vlogs together.

The two then-teenagers reunited in 2009 in the Disney Channel original movie, “Princess Protection Program.” In conjunction with the film, Lovato and Gomez recorded the song, “One and the Same.”

But a year later, the two besties seemed to have grown apart. Gomez started hanging out with Taylor Swift. And according to Elite Daily, Lovato was asked by the paparazzi how Gomez is at that time, and she replied, “Ask Taylor.” After hearing to rehab at the age of 18, Lovato reunited with Gomez at the 2011 Teen Choice Awards and the MTV Video Music Awards.

In 2013, Lovato spoke with and recounted a time when Gomez called her crying because she was so worried about her. “Fortunately, I have family and friends around me that are very supportive of me and my recovery and everything I stand for… Nick Jonas especially… And Selena… I was like, ‘Look, I should be the one crying, it’s all good!’ But she was so worried and ever since then we’ve gotten closer,” she said.

Lovato talked about her drinking and substance abuse struggles in her YouTube documentary. She also dished on her eating disorder, which she fought against for several years. “When I feel lonely, my heart feels hungry and then I end up binging and I don’t know how to figure out how to be alone,” she said.
