I think gaga tops all of them when it comes to her psychology in her interviews shes always using these big ass words and even twists her own tongue at time. Like remember that interview when she was wearing that white bed cover with a blonde lady looking like sia and she was trying to explain her artistic vision of artpop and just stayed silent for a complete minute because she didn't know what to say next or maybe had a hot flash, who knows. But jesus christ every interview with her sounds like a 2 hour session with dr.phil. 2nd to gaga is madonna when it comes to interviews.
