Could we be talking lipo, chin implants or lip injections? Read on...
When a sleeker-looking Bristol showed up Tuesday at the Candie's Foundation 2011 benefit gala at Cipriani in New York, tongues began wagging about what exactly is going on with her new look.
A source close to Palin insists to E! News that she hasn't gone under the knife and "isn't that kind of person" that would alter her looks with some help from professionals.
"I can tell you that she has lost a tremendous amount of weight since Dancing With the Stars and that is most likely the reason for the speculation," says the source.
Nonetheless, the 20-year-old's defined jawline, sky-high cheekbones and fresher looking eyes are now being dissected by one who knows best.
We sent before and after pics of Palin to Dr. Brian Glatt, a board-certified New Jersey-based plastic surgeon with more than 12 years of expertise, and here is what he told us:
"Her upper face, her eyes, brows, and forehead seem to be the same as they were," he says. "She's lost a little volume in her cheeks from weight loss, which you'd expect in someone young, but the lower third of her face is a dramatic difference. You could draw a line across the lower third, it's like two different people."
Glatt says some of the changes are attributable to weight loss, but he highly doubts the entire look is due to a new diet.
"She had a double chin before and that's gone now. It looks to me like she's had extensive liposuction throughout her neck, including under her chin, which has clearly been liposuctioned, it's obvious to me," Glatt insists.
"Her chin is a lot more defined, which can occur from aggressive lipo, but she may also have had an implant. Her chin is more straight and more defined afterwards, which really points to her having a chin implant as well."
As for her new-look mouth? There are two possibilities, but Glatt is leaning towards lip injections.
"Her lower lip looks a lot more full," he said. "It's pretty obvious to me that she's had something injected into her lower lip, nothing in her upper lip. If she had surgery recently, he lower lip could be swollen, but it looks injected, I don't think it's just from postoperative swelling, it's more prominent."
Glatt says that Palin has made some surface beauty changes too, like shaping her brows slightly differently and wearing more eye shadow.
"Overall, she went from having a square face to a heart-shaped face, and a heart-shaped face is considered more beautiful," Glatt says.
No argument from here. Any way you slice it, she looks stunning.
