Cardi and Megan's much talked about collaboration climbed all the way to the top of the Billboard chart on Monday, knocking Harry Styles' "Watermelon Sugar" out from the top spot. "WAP" is Cardi's fourth song to earn the coveted No. 1 spot — following "Bodak Yellow," "I Like It," and "Girls Like You" — and Megan's second after her "Savage" remix, featuring Beyoncé, topped the Hot 100 earlier this year in April.

Cardi B/YouTube The Aug. 7 release of the single and its accompanying music video was met with both praise and criticism thanks to its sexually explicit lyrics and proactive themes. The inclusion of reality star Kylie Jenner sparked an online petition to have her removed from the clip and Tiger King's Carole Baskin also slammed the video for its racy content and use of real wild cats, even though they were inserted with the help of technology.

"I feel like people be wanting to put female artists against each other. ... You know what I'm saying?" Cardi explained. "Every single time I feel like there's a female artist that's coming up ... I always see like little slick comments like, 'Oh, they taking over your spot. They taking over this. They taking over that.' And it just makes me feel like, damn, why it had to be like that? Because I actually like shorty music a lot. Why does it even have to be like that?"
