Olivia Rodrigo has just won three Grammy Awards this week, and she went straight to headline her first-ever "Sour Tour" show. To kick off her touring season, she paid tribute to two of the biggest stars in the music industry.
According to Billboard, the 19-year-old award-winning singer/songwriter started her first performance in a sold-out show in Portland, Oregon.
Rodrigo featured all of 11 songs from her debut album "Sour," and she added two cover songs from two of her favorite music acts.
The "good 4 u" songstress sang Avril Lavigne's "Complicated" and Veruca Salt's "Seether."
Per Rolling Stone, the Disney star sang "Complicated" as the fourth song on her setlist, right after her smash debut single "drivers license."
Rodrigo performed the song while sitting on top of a piano.
After performing a few more songs, like a mashup of "Enough for You" and "1 Step Forward 3 Steps Back," the singer performed her rendition of the alternative rock song "Seether" by Veruca Salt.
The singer thanked her mother for introducing her to the band during her performance, which potentially influenced some of her punk rock songs.
Veruca Salt has since reacted to Rodrigo's cover by posting a video on their Twitter account.

"We've been belting out #brutal and #good4u in the car nonstop for the past year. This made our day, @oliviarodrigo #seether #OliviaRodrigo #verucasalt #sourtour #SOURTourPortland," the band wrote.
Lavigne had also reacted by quote-retweeting a video of her performance, adding an orange and black emoji in the caption.
Rodrigo's Portland show is just her first, and she's set to embark on 39 more stops in the following weeks across the United States and Europe.
Holly Humberstone, Baby Queen, and Gracie Abrams remain her opening acts.
Tickets for her highly-anticipated tour started selling in December, but all of her 48 shows were sold out immediately.
The demand for her tour was so big that the ticket provider reported site issues at the time when passes for her event became available.
Many fans were disappointed not to get tickets for her shows as Rodrigo specifically chose small auditoriums for her shows instead of arenas because she didn't want to skip "any steps."
The "traitor" singer told her fans that there would be more tours in the future.
