Andy Cohen is really trying to stir up some drama between "Flip or Flop" co-stars and exes Tarek and Christina El Moussa.

Tarek guested on Cohen's SiriusXM radio show on Wednesday, where the Bravo star put the house flipper in the hot seat on everything from his ex dating one of their contractor friends to his testicle implant following testicular cancer.

"I think I’m taking a break from blondes. I think I’ll dabble in brunettes for a while," Tarek joked. "I'm looking for someone that's a lot of fun, a free spirit and is on the same page as me. I'm just traveling, living life and having a blast."

Both Tarek and his ex Christina are dating again but he said he has not "girlfriend" in the picture at the moment.

He added that it's "going to be a while" until he starts seeing anybody seriously.

And while he's keeping things breezy, Tarek confirmed Christina was dating a contractor friend of theirs, Gary Anderson. "She wasn't cheating on me," he told Andy, "He was at my home and behind the scenes, but I actually have not seen him since."

Cohen then made a suggestion, as a TV producer, that they have Anderson appear on Season 7 of their HGTV show to ratchet up the drama.

"I don't think that's gonna happen. That's probably not a good idea," he said with a laugh. "A couple 2x4s might fall over. Wrong network Andy!"

Cohen also said he should make a spinoff show with his new girlfriend -- when he gets one -- and see what Christina thinks. "Put us on Bravo and then we can have a little bit of fun," Tarek said.

As for how things are between them right now, Tarek said he's in "such a good place," adding "I do not hate her." He also said he doesn't get jealous about photos of her with other men and explained, "When we go to school activities, sporting events, we will sit right next to each other."

That being said, they don't sit around and talk about who the other is dating either. "We're going through this divorce thing, we're working together, I just really don't want to know what’s going on with her personal life," he said.

When asked about his recent battle against testicular cancer, El Moussa joked, "My friends call me the one-nut wonder now," before explaining that he did get an implant.

"Yeah, fake ball, and I asked for an extra large one," he said. "It's like an implant. I can't tell the difference."

He added that he's open with anyone he hooks up with now though. "I tell them anyway though because I'm pretty much an open book," he explained.

As for Andy, he ended it on this: "I did it with a guy who had one ball once and it was surprising that he had one ball."
