Miley Cyrus is a natural woman, y'all!
The 19-year-old singer-actress showed off some extreme cleavage Sunday at the CNN Heroes: An All-Star Tribute in Los Angeles. Wearing a plunging Robert Cavalli yellow dress, her buxom look led many to believe she'd had a boob job, but Cyrus says that's not the case.
"Thank you for the compliment, but these babies are all mine," the former Disney star tweeted. "I wish [people would] realize you don't have to be fake to be beautiful!"
"I'm 19!" she added. "BOOBS GROW, PEOPLE!"
Although Cyrus didn't enhance her assets through surgery in 2011, several other stars -- including LeAnn Rimes, Nicole Richie and Teen Mom star Farrah Abraham -- opted to go under the knife.
