Who Pissed Off Ciara?

So yesterday CiCi released this lil viral that's causing quite the stir. The song is called "Basic Instinct (You Got Me" and for the first part of the video CiCi takes a stab at rapping and a stab at SOMEONE in the industry. She raps ish like "See I was out buying Chanel bags, while I was doing that you turned up your swag (you got me)/ Yup, caught me slippin’, but get your hustle on shawty I ain’t trippin’/I let ya in the game free / shawty whole album sound just like me/ Say you weren’t talkin’ bout me, but I know that you was talkin’ bout me!"
Ugh....okay CiCi! Apparently people say she's goin in on Keri Hilson. My question is: why now??
