What's happened to Chelsea, lately?

Chelsea Handler is one of my favorite funny ladies, but I'm suspecting that she's had a little work done to her face. On a recent episode of Chelsea Lately, she was sporting a black eye, and even made a joke about it. Since then, I've noticed a difference in her appearance. It looks as though she might have had some filler injected in her cheek bones (or maybe even some cheek bone implants). I'm not opposed to cosmetic procedures or plastic surgery, but we definitely don't want our lovely Chelsea looking like she's had two Tupperware lids jammed into her face.

I've searched the web for any photos or news on this, but only found one Chelsea fan site that mentioned her black eye. Anybody else notice this?
