VH1 will air Love & Hip-Hop season 3 episode 12, titled, One Day At A Time on Monday at 8/7c.

In the preview clip that provides a sneak peek at tonight's episode, titled Eric and Tiffany Face Off, Rich Dollaz decides to confront Erica Mena for being intimate with Tiffany, another woman he dates off-and-on, behind his back.

"I knew that Erica and Tiffany were messing around," Dollaz told the cameras in his confessional. "But the reality is Tiffany's loyalty to me, made her call me. Erica's disloyalty to me allowed her to be deceitful."

"I'm sick of the lies, I'm sick of the deceit, I just needed her to come clean," Dollaz adds.

Dollaz brought the subject up with Mena at her lipstick line launch event and brought Tiffany along after the model denied the girl-on-girl affair.

"I'm feeling away, I'm feeling away about this relationship," Dollaz begins the chat with Mena. "If there's something that you need to come clean about, you need to come clean about it."

"Like what? I've told you everything you need to know," Mena asked him.

"This whole relationship has been a lie..Im trying to figure out if this shit is even real," Dollaz replied. "I don't know, you told me you don't f*ck with girls no more but you do."

Mena outright denied the claim.

"I'm gon' let you believe that, I'm gon let you believe that," Mena told him. "Why would I lie to you?" she asked him. "It's just lies, it's just lies," she added. "You assume..You assume and you're going off of hear say."

In last week's epiode, viewers learned that Dollaz convinced his on-and-off lover Tiffany to become friends with Erica Mena, in order to spy on her. In the process, Mena and Tiffany began their own relationship.
