Bobbi Kristina isn't happy about Angela Bassett not casting her in that Whitney Houston bio-pic.

Angela, who's directing the Lifetime movie, told Entertainment Weekly that she never considered casting the late singer's daughter in the lead role. "She’s not an actress," Angela explained. "I know she's acted here and there. I know she's been on their family's reality show, but she's not an actress and acting is a craft."

Bobbi responded with a barely readable tweet: "Ha MsAng 'bassketcase' has such a damn nerve my lord, at least the world doesn't mistake me for the wrong sex…she has some #XtraEquipment." She added, "When I win my first Grammy or Oscar, *Shrugs* hmm whichever comes 1st, I'll be sure 2shout URname out b-tch! Hah UrTestResults = Male. Lmao."

According to E! Online, former America's Next Top Model contestant Yaya DeCosta has been cast to play Whitney.
