Kim Zolciak's plastic surgery rumors are starting to swirl again in the media. The "Real Housewives of Atlanta" star is said to have different face features now, which is different from how she looked 14 years ago. Is she one of the stars who had undergone plastic surgery?

According to Radar Online, Zolciak, 37, seemed to have bigger lips now than before. The gossip site had the backup of a doctor named Dr. Westine who claim she might have undergone a series of procedures on her face such as enhancement on her lips and eyelashes.

"She likely maintains her lip volume with injectable fillers such as Juvéderm ultra or Restylane silk. Each syringe usually costs about $600 to $700 and lasts about a year in the lips," Dr. Westine said. "She appears to have lash extensions on or she may have been using Latisse to grow her eyelashes and make them longer and thicker."

Zolciak's plastic surgery rumors are not new. In 2009, the mother of six admitted that she had Botox for her migraines, E! Online reports. However, Westine believes that she might have undergone Botox not only for her migraines but to move her eyebrows. The doctor claimed there is more distance between her eyelashes and eyebrows and that her eyebrows appeared to have been pulled down. The lifting effect is a result of the Botox, the surgeon explained.

On Wednesday, Zolciak's plastic surgery rumors hit the social media by storm after she admitted on her Instagram account that she went under the knife for some reasons. "So you all know after the twins I had a hernia and while fixing the hernia I opted to have a tummy tuck as well!" Zolciak wrote in her selfie post. "My scar is very low and very thin much thanks to @drhochstein but I still had a scar. I could wear bikinis you would never see it."

Over the summer, Zolciak denied plastic surgery rumors, claiming she didn't have full surgery on her face. She dished she never had it done on her face. In an earlier interview, the 37-year-old actress confessed that she would love to have a nose job, but she fears of having one. However, she bravely admitted to having tummy tuck and multiple breast augmentations to allegedly feel like 20 again.
