Chelsea appears to have had orthognathic surgery. The surgery is performed by an oral and maxillofacial surgeon (a specialty in dentistry)to correct developmental deformities of the facial skeleton. Plastic surgeons generally do perform this surgery.

She had her father's bulbous nose - that has been refashioned to remove much of that. Her chin has been enhanced, and the jawline may have been retouched.

Open your eyes boys and girls. How 2 decent looking lyers could produce such an ugly daughter is amazing. Chin implant, weight loss, hair change, nose job. -- perhaps cheek implants?. She still has the big mouth her mother does.

Amazing what you can do when mommy and daddy have combined income of $109 million in 7 years.

Of course she has had surgery. Her nose is totally different, but the biggest difference is that she did not used to have a chin at all. She definitely looks better, but come on people get out of denial.

Yes, I think she's had work done, and she looks a million times better. Both she and her mother look much better as blondes.
