The model announced Aug. 11 that her father, longtime Rhode Island dentist Dr. John W. Moakler III, had died. He was 85.

"I am so thankful I got to have as many years with my parents as I did, and to have the time I had these last weeks with him."

Shanna's mother, longtime dental hygienist Gail Moakler, died unexpectedly in January at age 77 at a Rhode Island hospital, according to her obituary. In addition to the Miss USA 1995 winner, she and John are also survived by the model's brother John W.

"My father was an amazing husband, doctor and father he was more than anyone could ask for," Shanna wrote. "I will hold tight to the incredible life both my parents provided for me and the love and strength they instilled in me. The unwavering support at times when I didn't deserve it. I love you dad and my world will never be the same without you in it. I appreciate all those who have reached out and sent messages of support. Godspeed"

Shanna included in her post a photo of herself dancing with her father at her 2004 Nightmare Before Christmas-themed wedding to Travis Barker, with whom she shares kids Landon Barker, 19, and Alabama Barker, 17, as well as eldest child Atiana de la Hoya, 24, her daughter from a previous relationship with Oscar De La Hoya and who the Blink 182 drummer helped raise.

"I hope you can still have the love that I've had," John told them, "and I bless you."
