To paraphrase Dolly Parton, looking that cheap, well, isn't cheap. She's spent plenty getting work done on her face — and her famously ample chest. "I look at myself like a show dog. I've got to keep her clipped and trimmed and in good shape," she's said.

Jennifer Grey's "Baby" face is gone. The "Dirty Dancing" star, who openly regretted having her nose done in the late 80s, appears to have gone under the knife again. "Her lips appear to have been injected," Dr. Anthony Youn told RadarOnline.com.

The fashionista formerly known as Posh Spice has seen the plastic surgeon at least three times since she met husband David Beckham in 1997. She went from a 34A bra size to a 34DD and then back again.

Lacey Schwimmer, who was Chaz Bono's dance partner on Dancing With the Stars, got a hush-hush boob job, a source told People. "Lacey's told friends she got a boob job. She'd wanted one for a while so she went ahead and did it," the source said.
The model and actress is rumored to have had three breast surgeries to achieve her signature look. But you might wonder if she had some lifting done as well... we're talking about her face.

It looks like Jada Pinkett Smith's undergone a transformation between the March premier of "Madagascar 3" and the May premier of husband Will Smith’s "Men in Black 3." Her face seems thinner with more defined cheek bones, but could the rumored plastic surgery just be the result of her smirk? You be the judge.

Newton is pictured at left in 1990 and at right in 2011, at age 69. When Wayne was a child performer, he had to bleach his hair blond so he would be accepted by the public. Now he apparently has made even more changes.

The rumors are true: Bristol Palin’s new look is a result of going under the knife. The surgery, however, wasn’t cosmetic. Palin, in an interview with Us Weekly, said the corrective jaw surgery was “necessary for medical reasons,” reportedly to fix an overbite.

Sarah Chalke, who rose to fame playing the neurotic but hilarious Elliot in Scrubs, had a wholesome, girl-next-door look back in 2006.

But come 2011, there are some distinct changes. Though the actress hasn't admitted to going under the knife, her nose looks much thinner and her eyes look different.
It appears Lindsay Lohan's lips are growing along with her criminal record. LiLo showed up for her court arraignment on a charge of felony grand theft with what appeared to be a plumper pout. Lohan has denied having any injections to her lips in the past, but do you believe her?
Lisa Rinna, who starred with hubby Harry Hamlin in the TV Land reality show "Harry Loves Lisa," spent 20 years with a silicone-augmented upper lip gone badly awry. Her corrective surgery made for one of the show's main subplots and left her looking much better.
The operation was documented for the show, and Rinna warned young women not to have their lips fattened up.

Paris "the Heiress" Hilton has a face that's been imprinted on our brains. But there's another aspect of Paris that may have escaped notice...
Paris seems to make a bigger impression than she did five years ago. Could a mere push-up bra be responsible, or is there something more to it?

Hole frontwoman Courtney Love is at least as famous for her marriage to the late Kurt Cobain as she is for her role in The People vs Larry Flynt. But it seems her career wasn't the only thing that got a makeover after her grunge days...
