Jessica Simpson sparks cosmetic surgery rumours after Instagram post

Poor Jessica Simpson is facing the internet trolls... AGAIN!

The mother-of-two has long been known for her naturally flawless looks.

But after sharing a pouting photo on Instagram to celebrate achieving her goal of 12,000 steps a day, fans were quick to comment with concerns she'd undergone cosmetic surgery.

"Walkin' #120000Steps #SandpaperSmooch #ShowMeYourSteps," she wrote in the caption.

"Her fake lips are hilarious," one person wrote.

Another said: "Her bottom lip is so damaged. It looks like a butt now not a solid bottom lip."

"Her injections have damaged her lip. It’s a serious issue," a third commented.

The 37-year-old singer has previously admitted to trying lip fillers, but claimed that she hated the unnatural results.

"I had that Restylane stuff. It looked fake to me. I didn't like that. But it went away in, like, four months. My lips are back to what they were. Thank God!" she told Glamour magazine in 2006.

Simpson has yet to respond to the criticism about her lips.

But we think she still looks beautiful!
