Katy Perry opened up to Vogue about her relationships with Russell Brand and John Mayer. The singer said that she was in love with ex-hubby Russell when she married him, but she hasn't spoken to him since he asked for a divorce via text back in 2011. Katy added that she blaimed herself for their break-up until she "found out the real truth," which she "can't necessarily disclose." She also revealed that she was and is still in love with John Mayer and said that he has a "beautiful mind" and a "tortured soul." The July issue goes on sale on June 25th.
