We already know Ariana Grande from the hit teen TV series Victorious and its spin-off Sam & Cat, both of which see her play the bubbly and intelligent Cat Valentine as a supporting and then lead character, respectively.
Now, the 20-year-old US actress is making waves in the music industry too, ever since her debut album Yours Truly claimed the top spot on the Billboard 200 chart last week.
This makes her the first female artiste to head straight to No. 1 with her debut album since January 2010, when Kesha's Animal achieved the same feat.
Yours Truly's first single The Way, featuring US rapper Mac Miller, made it to the Top 10 of Billboard's Hot 100 chart, while her follow-up Baby I, peaked at No. 21.
She has called her success a "dream come true", adding to Billboard: "I'm happy to be taken seriously as an artiste and I hope to do music for a long time."
LOUD puts together a list of 10 things you need to know about the reigning queen of the US charts.
1 SHE IS THEATRE-TRAINED
In 2008, Grande had a head start in acting with her debut role as a cheerleader named Charlotte in the Broadway musical 13.
In fact, she did such a good job that she won Best Actress at the National Youth Theatre Awards the same year.
