The young celebrity has the Internet buzzing about these supposed before & after boob job pictures shown above.  The Sun, among many other sites, is posing the question to its readers and currently roughly 70% of the readers believe that she did in fact have a breast augmentation.

A boob job, or breast augmentation, is an operation to enlarge or change the shape of a woman’s breasts.  In recent years it has become one of the most popular and common plastic surgery procedures among women.

It looks like Nicole Richie, the famous actress, celebrity, and daughter of Lionel Richie, has gone under the knife to have a breast augmentation.  TMZ.com recently reported that the new mommy was showing off her new body and breasts at her husband’s event last night.

It is common for women’s breasts to become larger when they are pregnant, and even larger when they breast feed.  But as TMZ suggests, the before & after pictures above may be telling us the story of breast implants and not mother nature.

Christina Aguilera, the famous pop singer and recent mommy, is rumored to have had all kinds of cosmetic surgery procedures, including a breast augmentation that boosted her from A cups to C cups. Although the recent pictures of Aguilera’s breasts during and following her pregnancy look quite close to D cups.

She has denied the rumors and claimed to have never gone under the knife. Awfulplasticsurgery.com has pictures, shown below, that would indicate otherwise. As you can see in the photos of Christina Aguilera’s breasts below, there is a ripple which is commonly found with implants and capsular constructure.

Did she? Didn’t she? It isn’t 100% clear from the before & after pictures nor has she confirmed that she’s had breast implants.

As the photos above show, Gwen Stefani had very small A cup breasts but has been seen recently with larger breasts as shown in the photo on the right. A definite change in size as she was very small before.

Aside from Janet Jackson at the Super Bowl, no other actress & celebrity has received as much attention surrounding her breast implants as Tara Reid. Then again, not many show them off as much as Reid.

As the above before & after pictures show, Tara Reid had a boob job a few years ago but the procedure was not a success. In 2004, a wardrobe malfunction (see in the picture below) gave the world an up close view of Tara’s breast implants with visible scars and oddly shaped nipples.

Rihanna, the Grammy award winning singer, has apparently had a breast augmentation. Check out the before & after pictures above. We also dug up this “insider info” that was posted at Mediatakeout.com.

Katie Holmes had a nose job? Right? That’s the story according to Makemeheal.com and evaluations from a plastic surgeon.

A nose job is surgery to repair or reshape the nose and is one of the most common of all plastic surgery procedures. In this cosmetic procedure the nose is reshaped by resculpting the bone and cartilage in the nose.

Looking at the before & after pics you can see that Katie Holmes’ nose looks noticeably thinner and a completely different shape.

Kelly Rowland, the former star of Destiny’s Child, has been in the news with reports of a breast augmentation.

The paparazzi caught full breasted Rowland on the beach in Miami wearing the same purple bikini that made her look flat-chested last August.

Kelly Rowland is refusing to confirm or deny the boob job rumors but a leading surgeon insists the camera never lies.

Dr. Michelle Copeland tells Star magazine, “She definitely has significantly larger, fuller breasts now, most likely from implant augmentation. Some women want Wonder Woman breasts, which Kelly certainly has now.”

Lots of speculation regarding the famous singer’s nose. Has Beyonce had a nose job? The before & after pics seem to tell it all, although Beyonce has never admitted to having the plastic surgery procedure. But according to Life & Style Magazine Beyonce’s been playing Nip/Tuck with her nose

“There’s little doubt that she’s had rhinoplasty,” Chicago-based plastic surgeon Dr. Peter Geldner tells L&S.

“The nose is narrower and more refined with a clear demarcation of her dorsum (nasal tip.)”

“Her nasal tip was kept natural-looking without too much narrowing.”

Has Scarlett Johansson had a nose job? After quick glance at the before & after pictures above you may think so, but don’t rush to judgment too quickly.

Scarlett Johansson sued the US magazine because they showed two different pictures of the actress on a magazine cover that suggested she might have had rhinoplasty. Underneath the pictures inside the magazine is a telling quote from Scarlett : “I definitely believe in plastic surgery. I don’t want to be an old hag. There’s no fun in that.”
