The former country star took to Twitter to share her excitement after hearing the news.
"The Blank Space video just became the fastest to hit 1 billion views on @vevo," she told her 60 million followers.
"(And) Bad Blood is #1 at pop radio for a 3rd week. THANKS GUYS!!!," the 25-year-old singer added.
"Blank Space" was released late last year as the second single off Swift's massively successful fifth studio album 1989.
Its cinematic music video was directed by Joseph Kahn and was made available on Vevo last November.
