Well, in a recent interview with WHO magazine, leading Los Angeles based facial plastic surgeon Dr A. John Vartanian has spoken out about the celebs he believes has had work done.
The first star he pointed out was Modern Family actress Ariel Winter.
Dr Vartanian claims that she has had "lip enhancement, combined with good makeup, along with her natural weight loss, all better match her petite frame."
He also named Kendall Jenner as a plastic surgery candidate, claiming that the model has had work done on her gorge face.
"The work looks good from this angle. With her getting older, her face is leaning out, which complements her [look] well."
In the past, Kenny has firmly denied having work done.
"As a model, why would I have my face reconstructed? It doesn't even make sense."
Kendall reportedly followed in the footsteps of her big sister, Khloe Kardashian who the doc claims has also sat in the surgeons chair.
Apparently, Koko "most likely had a rhinoplasty (nose job)" and her lips "are way too over-injected," he added.
"One starts with a little filler, gets used to it and then asks for more, gets used to it and asks for more and so on and so forth until the 'trout pout' happens."
And lastly, the surgeon accused Miss Bella Hadid of having work done.
"Bella obviously has had a rhinoplasty," he says.
"Compared to her earlier photo, her nasal tip has elevated/rotated and been refined."
Bear in mind that this is just the educated opinion of an L.A. surgeon who didn't actually perform the surgeries himself.
But it's V interesting to hear his take on it all.
