SINCE going under the knife to remove silicone from her butt, Blac Chyna has been building up her body using battle rope and weights.
But a plastic surgeon has claimed a "lump of silicone" is showing at the top of the mom-of-two's thigh, instead of her desired new muscle.
Chyna, 35, has been sharing plenty of clips on Instagram of her weightlifting workouts.
These have come in the run-up to her appearance in a special ops-type reality show.
The videos show the influencer trying to sculpt her butt, thighs, and legs. She performs lunges, leg extensions, and curls.
A personal trainer can be heard saying: "Yes ma'am, come on! Go to work. Good s**t."
New York plastic surgeon said he noticed Chyna's lower physique did not look quite right.
He pointed out a “bulge” or “lump” that is visible in a video posted on August 19, at the top of one of the model’s thighs.
In an exclusive interview, Westreich told The U.S. Sun: “This is not an area where typically you are going to have that type of a shape.
"Chyna had the silicone removal surgery from her butt and appears to be doing aggressive workouts.

“This would not be the problem.
“She is trying to create the volume and shape with the muscle, since most of her silicone has been removed.
“If you do certain workouts, you can create a more lifted butt with the muscle strength.
“In the past, the silicone would have been injected into the soft tissue of the butt.
“If you look at Chyna's workout video, it does not appear as if all the silicone is gone.
“It looks like Chyna has a silicone lump still there.
“There is still some fairly significant volume at the upper lateral thigh, that does not look to be from a muscle.”
Chyna’s pricy cosmetic surgery efforts in March came after she ditched her OnlyFans account.
She reverted back to being called Angela White and opened up about her makeunder online.
Chyna told fans she had her silicone butt implants removed, a breast reduction, and was dissolving her facial fillers.
Speaking on , she said: “I’m just changing everything about me, It’s a dead end."
She added: "All that stuff is a dead end, and I know that I’m worth way more than that.”
Westreich suggested Chyna would need to return for more operations.
“Her surgeon would have to try and do another kind of suction removal,” he advised.
“They probably did the majority of it in the first one, but there may be areas where it is still there.
“She may have to go back for minor touch-ups and little removals.
“She would probably wait at least six months to let the swelling go down from the initial extraction.”
Westreich said there were different ways to remove the silicone from her butt and the filler from her face.
He revealed the latter can be dissolved using an enzyme.
“This enzyme breaks down the facial filler, " he added.
“But like the silicone in the butt, it is very hard to get rid of 100 percent of it.
“Most of the time you are going to be getting rid of just a portion of it.
“It also depends on how much of the dissolving agent you are willing to inject at a time.
“Most people are not going to be super aggressive with these dissolving injections.
“It is also hard to know how much you need to remove.
“I would expect somebody trying to get rid of all their face fillers to probably never be able to get rid of 100% of them.
“Blac Chyna would probably have to go back multiple times and have areas retreated where the enzyme given was not enough."
Chyna shot to fame as Nicki Minaj’s former body double before going on to date Rob Kardashian.
The influencer admitted to undergoing four boob jobs, getting lipo, and having silicone butt injections when she was 19.
Chyna shares daughter Dream, six, with Rob and her 10-year-old son King Cairo Stevenson with her ex-fiancé, Tyga.
She is now set to appear on season two of Fox’s Special Forces: World's Toughest Test.
The reality TV competition premieres on Monday. The lineup includes Jack Osborne, Tom Sandoval, and Brian Austin.
The celebs ditch their luxury lifestyles and do a 10-day special ops challenge.
Westreich suggested Chyna’s training and weight loss have also changed her facial features.
“She is undergoing weight loss and has a facial transformation from the filler removal there as well, “ he said.
“As you get thinner then a lot of times you will begin to see those muscles around the mouth.
“People have a natural kind of prominence around the mouth and it is just from the muscles of the mouth.

“But now that they made that smaller, it sort of looks a little unbalanced.
“The body changes are a waiting game.”
