What the hell happened to Nene Leakes' nose!

The reality star has been quietly debuting her new look about town -- and people can't help but to notice that she looks completely different!

As far as we can tell from photos of the former Real Housewives of Atlanta star -- it appears as if she's gone under the knife and had ANOTHER nose job.

If we look at older photos of Nene her nose is much wider and her tip much more pronounced than the images that have shown her with a radically reduced nose.

Page Six chatted up Dr. Matthew Schulman, a board-certified New York City plastic surgeon (who isn't the star's doctor) but said, “NeNe appears to have undergone nasal reshaping. She has likely had the hump removed and her nasal tip lifted and narrowed. This was probably accomplished by removing some bone and cartilage from her nose.”

The doc also added that the cost for a procedure like that would be $9,000 to $12,000 and recovery time usually ranges from several weeks up to a full year. Since Nene's nose only looks different in recent weeks we can assume she had the surgery quite recently -- so it's very possible that she will look even different after the swelling goes down even further.
