Heart added, "And she was trying to be my friend. Be nice to me."

Benzino then revealed that Hernandez went as far as sending a woman to attack Heart at Stevie J's club opening that aired earlier in the season.

"People don't know that the girl that got hit in the head with the bottle, Joseline brought her [Sabrina] there to turn up."

Benzino went on to claim that Hernandez was under the influence of drugs at the time as well. He said he knew that Hernandez set Heart up because the mystery woman, Sabrina, got so upset with Hernandez that she ended up telling him.

"She told me not even two weeks ago because Hernandez did her so dirty. She said 'We came in there to start it with Althea.'"

Heart finished the story and said that "grimy and sneaky" Hernandez consistently threw shade at her.

The reality TV couple added that Hernandez is threatened by Heart. They also admitted that Stevie J hasn't admitted to sleeping with Heart (before she was with Benzino) because he is set out to make a fool of Hernandez.
