Katy Perry Calls Madonna "Mom" On Stage; Grinds All Up On Her

#UnapologeticB*tch...es

Last night, during the Los Angeles stop of her Rebel Heart Tour, Madonna invited fellow pop star Katy Perry up on stage for a little "mother-daughter" bonding.

But wait, your astutely wondering, Katy Perry is the daughter of two Pentecostal pastors and Madonna... she once seduced a black Jesus.

"Mom," is apparently Perry's nickname for The Queen of Pop, who invited the "Roar" singer up on stage for a little bump and grind – including taking shots from a flask shaped like a banana (because... penis).

Of course, Madonna took the necessary opportunity to bounce up and down around Perry, who made an admirable effort to match Madge's seasoned stage bravado.

Also in attendance: Sean Hayes, Selma Hayek, Ashton Kutcher, Mila Kunis, Kathy Griffin, Fergie and Queen Latifah.
