Viewers saw Erica Mena's huge fallout and split with her now ex-girlfriend Cyn Santana on Monday night (Jan. 5) episode of VH1's Love & Hip Hop New York; just hours before Santana took time to slam Mena for her new engagement to actor and rapper Bow Wow.

"We're being honest here...I was very confused at first," Santana told Hot 97 in New York City. Mena announced her engagement to Bow Wow just weeks after breakup with Santana.

Interestingly enough, he was also a topic the two often argued about after Mena kissed him on BET's 106 & Park.

Santana continued and said, "You know, when they did the whole '106 & Park' kiss, I was thrown off. I know Erica is spontaneous and crazy. That's one of the things I liked about her. She did that, and I was like 'okay, I didn't find that funny. Don't make me look crazy, like, let me know first.'"

She added that while Bow Wow claims he and Mena have been close for years, she said she was still thrown for a loop.

"I never imagined her getting engaged so quickly."

As far as whether she believes the future wedding is real or just a publicity stunt, Santana confessed she believes it's valid. But was unsure if their marriage would last.

"I think it takes a lot to deal with Erica."

Still, while she shared her thoughts on Mena and Bow Wow's engagement, she made it clear that she would be over it if she did not have to go through the situation once a week.

"No, no I'm not [happy with Erica]. This is the hardest part, you get through the s---, now you have to relive it again. Erica and I stopped talking a long time ago. Now I have to sit here and watch it every Monday. I'm so past that. She's past it. She's moved on, I've moved on."
