Ray J has let it be known that he wants his sister Brandy to do a joint tour with Monica, but Monica didn't appreciate him talking about her.

Both women have a long history together:  They had beef at one point and collaborated on the 1998 hit, "The Boy is Mine."

"BRANDY/MONICA TOUR," wrote Ray under Monica's livestream, per AllHipHop. "PLEASE LETS MAKE HISTORY, ONE RUN FOR THE FANS. 100M plus for you both."

Again, Monica wasn't pleased with the comment and told Ray J to pipe down.

"I’ve been repeatedly contacted about interviews where my name and tour possibilities are being discussed. I’ve not received any contracts or calls about said tour," she wrote on Instagram Stories. "Ray J – I’m kindly asking you to stop speaking on me in public! A private conversation would be both necessary and respectful! Brandy is a LEGEND! She’s one of one with an extensive catalog that I deeply respect and a voice sent from heaven!"

"The conversation being had without she and I is beginning to muddy the waters severely!" Monica added. "She and I are both consummate professionals that share a massive recording as well as an entire era! Please allow this to remain positive and beautiful."

Do you think Ray J will comply with Monica's wishes?
