On Friday, Britney made the rounds with radio stations all over the country to promote her Las Vegas residency, the “Work Bitch” music video and her upcoming studio album. During her first Houston interview (with Hot 95.7), Britney would pause before answering each question for reasons unknown. After she said her goodbyes, the radio hosts trashed her saying “those meds blocked her hearing” and she didn’t answer fast enough because has voices in her head.
