I think she's frustrated right now with a number of things. Her album is not doing as well as she hoped, Jay-Z seems more focused on Rita Ora right now, she's constantly being asked about Ashton Kutcher in just about every interview as of late, and she's gotten plenty of flack for recording with Chris Brown recently. I think she's just acting out. If she doesn't straighten up her act, the "PTB" will really be on her case.
