Ariana Vs. Big Sean: She Fires Back

Ariana Grande’s camp claims she’s the one who called it quits with Big Sean.

Sources tell TMZ the last straw was when Sean dropped his track, “Stay Down,” in which he raps: “I ain’t even gonna lie, I got a million dollar chickWith a billion dollar p****y…”

Ariana felt humiliated because Sean was treating her like a piece of meat. Ariana’s grandmother came to her and asked about the lyrics, which was especially embarrassing.

But there was tension leading up to the song. Sean claims she made him pay for all sorts of extravagances. But Ariana sources say SHE is the one who foot most of the bills, including vacations and private flights.

Also, Sean complained that Ariana didn’t show up for his big House of Blues performance in February because she selfishly cared more about her Grammy’s performance the following day. Ariana sources say on Saturday, when she rehearsed, her voice was strained and her vocal coach ordered her not to even speak for the rest of the day, and Sean got pissed.

As for Sean saying Ariana set up the Bieber stage grab to humiliate her, Ariana says they were already broken up and she did NOT ask Bieber to engage in a stunt. And she says Sean never even brought it up.
