Kelly Osbourne documents struggle with sample size dress -- See the candid pic!



Kelly Osbourne isn't a big fan of sample sizes.

Ozzy and Sharon Osbourne's 32-year-old daughter took to Instagram on Friday to share a hilarious pic of herself struggling to get out of a dress that just didn't fit.

Osbourne definitely isn't afraid to keep it real. In an interview with ET in April, she opened up about her past drug abuse, and how she and her family hope their experiences can help others.

"When you love someone and you understand someone and what we have been through in my family -- between my mom's cancer; my dad's Parkinson's, coma, bike accident, addiction; my brother's addiction, MS; my Lyme disease, addiction -- we've been through so much together and supported each other through everything," she said.

"We are not perfect, we are never going to be and we do not want to be," Osbourne added. "If we can share our pain with others, so people think they're not alone then that's what we would rather do and turn it into a positive and just keep loving and moving forward."
