You Decide: Do These '90s Stars Look Better Now or Then?

Was it just us or did the 2015 American Music Awards roster seem like an awesome '90s reunion? Several icons of the decade showed up for the telecast. For instance, beloved pop star Paula Abdul presented Ariana Grande with an award (this was hot on the heels of the news that all original American Idol judges will be returning to the last season of the show). Alanis Morissette celebrated the 20th anniversary of her hit single "You Oughta Know" by performing it with Demi Lovato, and Celine Dion brought the audience to tears with her rendition of Edith Piaf's "Hymne a L'Amour" during a moving tribute to the Paris attacks. Alicia Silverstone, Jenny McCarthy, Gwen Stefani, and of course the night's stunning host Jennifer Lopez were there, too.

After seeing all of these women (and more!) looking gorgeous tonight, we thought an official trip down memory lane was in order. Some of their transformations are mind-blowing! Take a look at their photos from yesteryear, then let us know whose look you favor — then or now? — in the comments.

Let's just say Jennifer's assets still look phenomenal, 16 years later.

Now, Gwen plays up her eyes with liner and loves a good nude lip, too.

Today, Celine's longer, lighter hair accentuates her face. The beach waves feel soft and romantic.

Jenny McCarthy, 2015

Told you! She's definitely going more glam with her eye makeup and probably has several rows of extensions in, but the woman looks great.

Alanis Morissette, 1999

The Tangle Teaser wasn't invented in 1999, which makes me concerned for Alanis in this photo. Her mermaid-length locks must have been tough to brush through!

Significantly shorter hair makes Alanis look totally chic.

I can't choose which photo is better. Alicia, time was good to you!

Just like Celine, Paula's current look outshines this one, but how sweet was she?
