Once you were finished picking your jaw up off the floor following his performance of "i" earlier in the show, you might have asked yourself the following question when Kendrick Lamar came back for round two on "Saturday Night Live" this weekend: who WAS that woman?

You know, the one who kicked off the new song "Pay For It" with the powerful opening, accompanied only by her own spare keyboard playing? She wailed the hook in a scratchy voice before Black Hippy's Jay Rock came out to drop his first verse on his tune featuring K-Dot.

Well, here's everything we know so far:

She's huge In Canada, eh?

Her name is Chantal Kreviazuk (Chantal means "to sing" in French!) and while she's not as well known in the U.S., she's been a star in her native Canada for nearly 20 years.

She started playing piano when she was 3.

The classically trained pianist from Winnipeg -- who won numerous piano competitions as a self-taught child prodigy -- scored her first contract with Sony Music before she even played a single live show.

A motorcycle accident changed her life.

Having already decided to take a turn from classical to pop music writing in college, her life was changed forever in 1994, when she was in a terrible motorcycle accident in Italy that left her bedridden for several months with a broken jaw and broken leg. During her recuperation, she signed with Sony and began shaping the songs on her introspective 1997 debut, Under These Rock and Stones.

You have 100 percent heard her songs in a show or movie you love.

Though well-received, her debut album didn't take off. But a year later, her cover of John Denver's "Leaving on a Jet Plane" appeared on the hit soundtrack to the movie "Armageddon," which helped get her noticed down south.

It also led to tons of other soundtrack work on movies and TV shows, including "Feels Like Home," "Everwood," "Dawson's Creek," "Joan of Arcadia," "Sisterhood of the Traveling Pants," "How to Lose a Guy in 10 Days," "Confessions of a Shopaholic" and the theme song for NBC's "Providence."

You definitely remember her song in the trailer to 'Saved'

Her moving ballad "In This Life" was a huge part of the 2004 comedy "Saved!," which starred Jena Malone and Mandy Moore (who Kreviazuk later wrote songs for).

She's kind of like royalty in Canada.

Married to another household name in her home country, Our Lady Peace singer/songwriter Raine Maida, Kreviazuk has had a solid side gig co-writing by herself and with her hubby on songs by everyone from Drake ("Over My Dead Body"), Gwen Stefani ("Rich Girl"), Shakira ("You Don't Care About Me") and Kelly Clarkson ("Walk Away"), as well as songs by Jennifer Lopez, Carrie Underwood, Avril Lavigne, Mandy Moore and Hilary Duff.

She almost tossed 'Pay For It' in the trash.

To date, she's released five solo albums and though many Americans might have been trying to Google her name when they saw her on "SNL," she's actually a big part of "Pay For It."

Even with all her success in Canada and the U.S., Kreviazuk couldn't believe she finally made it to the big show to sing the tune she co-wrote with the Black Hippy members. "The whole 'SNL' experience was obviously incredible, but honestly not until up on stage at the end, talking and hugging [the cast], that's when it was like, 'Wow, this is THAT SNL, the one I grew up watching. Wow.' That was surreal," she told The Hollywood Reporter on Sunday morning.

"I don’t write [Jay Rock's] thoughts, I write my own. I wrote the hook, I wrote the melody. I wrote the music and then I track it and then they chop it up and then keep going with it. I kind of thought this one was in the dumpster. ... I put a lot of things in the dumpster and that one I just let go of completely," she said of the song that she had tossed to the side until Lamar and Rock saved it from the trash heap.

"Then, one day I heard that they were going to have Kendrick and Jay Rock put a verse on it, and then I heard they were going to keep me as a feature, which was incredibly humbling and special and really super gracious, and then the next day it was in a Beats commercial."

There's already another new song on deck

Kreviazuk wasted no time with her huge "SNL" exposure, releasing the new single, "I Will Be," soon after her appearance.
