It looks like Miley Cyrus’ baby sis Noah Cyrus is once again sparking plastic surgery rumors! In snaps from her 18th birthday celebration, the teen was sporting some noticeably fuller lips, and fans couldn’t help but wonder if she got a little enhancement. Watch the video below to see the pics for yourself!

People have been noticing the singer’s changing looks for some time now. Just last year, In Touch spoke to multiple plastic surgeons — who haven’t treated Noah — to get their thoughts on the type of procedures she’s likely had done. “She has significantly increased facial volumes (cheeks, upper and lower lip, and chin) and her eyebrows appear to be higher,” double board certified plastic surgeon Dr. Vartan Mardirossian said. The doc also speculated that she may have gotten botox to lift her brows, and pointed to the possibility of fillers, fat grafting, and facial implants, which would explain the plumpness in her face.

Dr. Andrew Miller, a board certified facial plastic surgeon, agreed with the fillers prediction. “It looks like she may have had fillers in her cheeks and lips and possibly a chin implant,” he explained. “Instead of fillers, she may have had cheek implants.” Noah herself has not addressed the rumors. Do you think she’s gone under the knife?!
