However, Brooke, who brought her dad to the event on Thursday to celebrate his 58th birthday, says her father was simply showing parental support.
"[I'm] SO sick of people saying me and my dad are in some perverted relationship!" the aspiring singer, 23, Tweeted on Saturday. "Go home and do your own thing!
"Stop picking on me!" she added.
The black and white portrait (which shows Brooke posing nude inside of a cage, but doesn't reveal any private parts) is meant to raise money for animal activist group PETA - a cause dear to the 23-year-old's heart.
"I've always had a love for animals, and I've seen abuse firsthand. It ignited my passion for saving them even more," Brooke, who, in addition to her father, also brought her beloved Pomeranian to the unveiling, told the Miami New Times. "I have a Pomeranian... and once you know how emotional and intelligent they are, it's hard to know that they are hurting around the world.
"The worst part is that they are voiceless in our world, so it's our job to stand up for them," she added.
