She's 43 and more gorgeous than ever!

Alanis Morissette was nearly unrecognizable on Sunday as she took to the stage at California's KAABOO music festival -- and while her new look is a shock, we absolutely love it.

When the singer shot to stardom in the '90s, she was as known for her music as she was for her ultra-long dark brown hair. Two decades later, she's now rocking bleach-blonde locks at a much more manageable length. But don't worry: The hair may haev changed, but she's still got her kick-a** rocker style.

Take a look at her evolution in the slideshow below. Honestly, the icy blonde shade suits her!

Morissette performed a slew of her hits, including "Ironic" and "You Oughta Know," for a crowd that couldn't get enough. And she was loving it, too: According to reports, the star couldn't help giggling when she accidentally stumbled over a lyric.

It was especially great to see Morissette in such a good mood given that in early September, she opened up about the "crippling" post-partum depression that struck after the births of both of her children.

“There are days I’m debilitated to the point where I can barely move,” Morrissette, who is still battling the depression more than a year after welcoming her second child, told People.
