We've always given Kandi Burruss's fiancé Todd Tucker the benefit of the doubt (sorry not sorry, Mama Joyce), but we're having second thoughts after tonight's all-new episode of Real Housewives of Atlanta on January 19…

It all happened when Cynthia Bailey invited friends Natalie and Christopher out for a cocktail to celebrate her third wedding anniversary with hubby Peter Thomas. When the convo turned to our girl Kandi, Natalie dropped a major bombshell about Todd's past, claiming that he cheated on his ex-girlfriend — repeatedly!

"Actually, I know Todd," Natalie revealed. "He used to date my girlfriend Ani."

That's fine. Everyone has a romantic past, right? Unfortunately, Natalie has some bad news about why that relationship didn't work out.

"The Todd I knew back in the day. He was young and he was always cool, but he broke her heart a couple of times," Natalie continued. "She really cared about him. She was in love. And because of his activity she had to move on."

At this point Cynthia needs clarification — and so do we! Did Todd cheat her?

"A couple of times," Natalie confirms. "Todd has a street hustle, don't ever get that twisted. Todd knows how to find himself in situations to better himself."

In other words, this dude's a total opportunist — just like Mama Joyce said.

The drama continued later in the episode when Natalie joined the girls for a trip to the vineyard and dished about her knowledge of Todd's past — in front of Kandi! (So not cool, by the way.) But the "No Scrubs" songwriter didn't let Natalie's gossip shake her confidence.

"I'm successful, I can't help it. And I look good," Kandi fired back. "That means he has no reason to cheat. He came up! Give it up for Todd!"

So does that mean Todd gets a free pass? Well, before we go ahead and accuse him of being a cheater, we have to consider that this rumored "activity" happened ages ago, long before he ever met Kandi. Plus, how credible is this Natalie woman anyway? On the other hand, we can't help but wonder if Mama Joyce was right about Todd all along. Nothing like a mother's intuition, right?

What do you guys think? Is Todd trustworthy, or should Kandi kick this scrub to the curb? Weigh in below.
