Has Noah Cyrus gone under the knife? The beautiful little sister of Miley Cyrus has sparked speculations she's got plastic surgery done with her "changing look." According to a new report from In Touch, many believe that the "Make Me (Cry)" hitmaker's changing face "is the result of more than just puberty."

Several plastic surgeons, who haven't treated Noah, have revealed to the publication about the changing look of the singer who is currently still 17 years old. Double board certified plastic surgeon Dr. Vartan Mardirossian told the news outlet, "She has significantly increased facial volumes (cheeks, upper and lower lip, and chin) and her eyebrows appear to be higher."

The plastic surgeon speculated that Noah might have had botox to lift her eyebrows. It's also possible that the aspiring singer might have had fillers, fat grafting and facial implants to make her face and lips look plumper.

Agreeing that Noah's new look was possibly the result of fillers and implants, board certified facial plastic surgeon Dr. Andrew Miller said, "It looks like she may have had fillers in her cheeks and lips and possibly a chin implants," before adding, "Instead of fillers, she may have had cheek implants."
