Why is Mary J Blige Beefing with J.Lo?

Rumor has it that R&B diva Mary J Blige may have some issues with Jennifer Lopez’s Vegas residency, which Mary feels J.Lo stole from her.

Crazy Days and Nights was quoted as saying:

‘Which R&B songstress has been bitching to anybody who will listen about that diva who snagged that Vegas residency that was all but planned for singer #1? She also has been whining about how singer #2 never sings live and she would never lipsync.’
