Amber Heard's recent divorce filing and abuse accusations against estranged husband Johnny Depp can't be easy for any of their family members, but that doesn't mean their loved ones are sitting back quietly.

Johnny's daughter, Lily-Rose Depp, took to Instagram on Sunday to defend her father, sharing a heartfelt message along with a precious photo of the pair from when Lily-Rose was a baby.

"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," the Yoga Hosers star wrote.

While some fans slammed the throwback pic, many more were supportive of both Johnny and Lily-Rose, with comments like, "I love you and your father. Sending more support than you can imagine!!!!" and "We believe in justice. Your father deserves all the support and love."

French-born Lily-Rose and her brother, 14-year-old Jack, are Johnny's two kids with ex Vanessa Paradis.

The father-daughter duo have always been supportive of each other. In fact, just last week, Johnny gushed to ET at the Los Angeles premiere of "Alice Through the Looking Glass" about how proud he was of Lily-Rose's new Chanel modeling campaign.

"I'm incredibly proud," the proud papa shared. "I didn't expect that all this soon. She's handling it beautifully."

"She has a good head on her shoulders," he added. "She's very flattered, and she's doing a great job."

The 17-year-old actress hung out with her dad and Amber as recently as January, when the trio took in Stella McCartney's Autumn 2016 collection at Amoeba Music in L.A. They posed for photos with Stella and Orlando Bloom, and Johnny even took the stage for a surprise performance with Marilyn Manson.

Amber was granted a temporary domestic violence restraining order against Johnny on Friday, less than one week after she filed for divorce from the 52-year-old actor.

As ET previously reported, the 30-year-old actress and her lawyer provided a photo to the Los Angeles court that showed various bruises on Amber's face, alleging that Johnny had harmed her. In her restraining order filing, she also detailed the alleged verbal and physical abuse she claims Johnny inflicted on her throughout their relationship.
