Pink, Beyonce and Lady Gaga. I respect and admire their work ethic, artistic integrity, diligence and overall involvement in every step of their work.
I put Beyonce ahead because I'm not here for pseudofashion shiz which takes up most of Lady Gaga's portfolio and because Beyonce seems to be much more involved vocally.
Pink, on the other hand is on whole another level; because her self-discipline and determination extends beyond the emotional, temporal and vocal demands. She gives her best to keep at her physical peak. (When on tour she worked out for about an hour, did yoga for an hour and ~2 hour show with several stunts every day, she does vocal warm ups on treadmill because of her asthma etc.) Basically she's been fit as **** for 10 years, ate and lived well (not to forget about pregnancy she had). She's not just the most talented performer, popstar and role model but an athlete too

Maybe lessors could promote as hard as her but never as efficiently and effortlessly
