Did you catch the new "90210" last night on the CW? What did you think? We thought original 90210 stars Jennie Garth and Shannen Doherty looked amazing! Although ... I couldn't help but notice how much their faces have changed over the last 10 years. Perhaps it's the hair or makeup ... or perhaps it's something else? Have a look:

Thoughts? I'll see if I can dig up photos of Shannen next week.
