Lily-Rose Depp, 17, shared a childhood photo of herself and her dad.
"My dad is the sweetest most loving person I know, he's been nothing but a wonderful father to my little brother and I, and everyone who knows him would say the same," she wrote in the caption.
Lily-Rose Depp is the actor's child from his 14-year relationship with Vanessa Paradis. The two are also parents to 14-year-old Jack.
She posted the photo days after Heard, 30, filed for divorce from Depp, 52, after 15 months of marriage. Two days later, Depp filed too. The pair have no children together.
It also comes after the actress was granted a restraining order against Depp, alleging physical abuse. Meanwhile, Depp's lawyer wrote in court documents obtained by ABC News that "Amber is attempting to secure a premature financial resolution by alleging abuse," and Depp "has every intention of staying away from Amber" as he's working out of the country.
Heard seemed to be in good spirits Saturday as she was photographed laughing and embracing a female friend in Los Angeles, according to People magazine.
In Europe, Depp played with his band at the Rock in Rio concert in Lisbon, Portugal, The Associated Press reported.
ABC News reached out to Wasser along with representatives for both Depp and Heard for comment, but they did not immediately respond.
