What comes to mind when you think about celebrities in beauty ads? Maybe the latest face of CoverGirl? Perhaps Kerry Washington's longtime partnership with Neutrogena? One of the numerous actors and actresses who've done campaigns for Proactiv, perchance? No matter what pops into your head, we bet it isn't what's in the slideshow ahead.
It just so happens that some of your favorite celebs starred in ads for beauty brands in the '90s and '00s — and, boy, are they a blast from the past. Now, we know it's far from practical to invest in a beauty product just because a celebrity claims to use it. But still, it is fun to look back on ads from years gone by.
Click through to see some of the lesser-known celebrity beauty endorsements through the years.
Christina Aguilera has her own perfume now, but in 2000, she served as the face of a different cosmetics company.

Tyra Banks taught the world how to smize. But do you remember her starring in beauty ads?

Banks was a CoverGirl. Fun fact: When Janelle Monáe later became a face of the cosmetics line, she told Vogue that she had admired Banks' ads growing up.

But *NSYNC starred in an ad for Herbal Essences. Because everyone wanted to copy Chris Kirkpatrick's hairstyle.

Some have noticed that Bledel's pose in this ad for Naturistics Lip Sparklers resembles that of Simpsons character Mr. Burns.

DJ Mark Ronson may seem like an unlikely candidate to serve as the face of a beauty brand, but the explanation makes perfect sense.

In 2012, Ronson starred as the face of Fendi's first fragrance for men. Vogue Paris reported at the time that the brand "wanted a man who is both modern and rock-'n'-roll, capable of embodying Fendi's own view of masculinity according to: seductive, unique, vibrant, and chic."
