Rapper Waka Flocka better go home and make sure that his wife Tammy, hasn't packed her bags and left him FOR GOOD.

Yesterday Tammy Rivera went to Teyana Taylor's concert - and Teyana pulled Waka's wife onto the stage, and gave her a sexy lap dance.

And we have to admit, Teyena definitely knows what she's doing.

Here's the video:

Teyana is openly bisexual - and possibly Tammy as well.

Last week, Tammy - who stars on the reality series Love & Hip Hop - appeared to say that bringing other women into the bedroom would be good for her marriage .

Tammy's revelation came after a woman on Twitter asked whether her followers "really wanna get married and have sex with the same person for the rest of your life."

R&B singer Brittany B responded that she would want to be involved in a monogamous marriage, as long as she could "add a few plus 1s to the party every now and then." Meaning that she wants to experiment with other lovers during her future marriage.

Immediately afterwards Waka Flocka's wife chimed in - and she co-signed Brittany's 'open marriage' plans. Tammy wrote about Brittany's swinger comment with, "I approve this message."
