The 24-year-old, who released her fifth studio album, 1989, on Oct. 27, celebrated the sales with a comical Instagram video of herself lip-synching to Kendrick Lamar's "Backseat Freestyle."

"Industry experts predicted 1989 would sell 650k first week. You went and bought 1.287 million albums. AND IT'S GOT ME LIKE," she wrote as the caption.

Taylor Swift Explains Her New Song Out Of The Woods

During her recent interview with Rolling Stone, Swift revealed Lamar's song is her "go-to" track to help her go from "feeling victimized to feeling awesome." Clearly she wasn't lying.

Swift's new album - which was also leaked before release - received an overwhelming amount of positive reviews from critics. New York Times critic Jon Caramanica said, "On this new stage, Ms. Swift is thriving. And crucially, she is more or less alone, not part of any pop movement of the day. She has set herself apart and, implicitly, above."

It was also praised by tons of celebrities, who took to Twitter to commend the songstress.

"My favorite songs on #1989 are This Love, Blank Space, Out of the Woods and also every single song," actress Lena Dunham wrote.

Actress Lucy Hale also said, "I know I'm late to this but @taylorswift13 1989 is perfectly written, perfectly produced & obviously perfectly relatable. Just so...good."
