Over the years, there's no doubt that Oprah Winfrey's look has changed dramatically -- you can check her out right now at StyleList's Look of the Day. Her hair, her weight, her wardrobe -- they've all been switched up on a yearly basis. But, has she gone under the knife to make more drastic changes?

Many experts say no -- as a matter of fact, although the look of her face has changed somewhat throughout the years (most notably, her schnoz), it's more a matter of makeup and lighting than surgical intervention. Because, let's be real, folks -- how many of our faces don't look considerably different now than they did in the '80s?

There's a great line in the play Cyrano de Bergerac where our big-nosed hero, Cyrano, tells his friends that despite what others might say, he believes his famously large honker is actually the source of his strength and virility.

Apparently, the British model Sophie Dahl, granddaughter of writer Roald Dahl, needs to bone up on her 19th-century dramas because girlfriend has serious desecrated the nose her parents gave her (right photo from 2001). As you can see from the recent photo on the left, Sophie's nose is teetering perilously close to Michael Jackson status, which is really a shame because she has a truly interesting, beautiful face.

But you know what they say, "Once you go Jacko, you never go backo."

Of course, Sophie Dahl isn't the first woman out there to go overboard with rhinoplasty. I've collected some of my "favorite" celebrity nose jobs in a gallery for you to check out. If I left one out, leave a comment, and I'll add it to the collection.
