Toni Braxton and Birdman

Toni Braxton and Birdman in Brooklyn (May 8, 2016)

*Toni Braxton apparently puts more than just respek on Birdman’s name.

According to TMZ, the Cash Money CEO showed up at her Grammy Park performance in Brooklyn on Sunday, and things got rather cozy backstage.

“Backstage was sealed off so very few people could see them together,” reported TMZ, adding that the above pic of the two from Sunday ended up on Instagram:

Sources tell TMZ … Birdman left with his entourage to go clubbing. It’s unclear if he and Toni had a “run-in” later, but we’re told they’ve been close for years … and have hooked up in the past.
