"Drivers License" also landed on top of several music charts in the United Kingdom and Australia, reports Billboard. The U.S. charts will be released Saturday, Jan. 23, but predictions are already in that Rodrigo will dominate the Hot 100 as well.
The fame was sudden for the teenage actress, who recently opened up to the UK's Big Top 40 and said her instant stardom "is just so surreal."
While she feels "grateful" for the support, she says nothing compares to landing on Swift and Horan's radar.
"The fact that [Niall] reached out to me was amazing," Rodrigo said. "We've actually been texting and he's like, giving me advice on all of the craziness in the music industry, so it's been really amazing."
