There were many new and interesting developments in the Season 8 premiere of The Real Housewives of New York City, one of which was the fact that Luann de Lesseps moved in with Sonja Morgan after she let go of her New York apartment. "I was actually staying with her while I was looking for an apartment this season," Luann told PEOPLE at the RHONY premiere party Wednesday. "She has that big, rambling townhouse. Her daughter went to boarding school. My kids were both at college – Noel went to college – and I thought, 'You know what, I'm going to stay with Sonja.'"

As we also learned from Bethenny Frankel and Ramona Singer in that same episode, Luann and Sonja have been going out and enjoying themselves lately, so we can only imagine the kind of fun shenanigans these two have gotten up to as roommates. 

For proof of that, you needn't look any further than the above exclusive video clip of the pair doing things that all roomies do. You know, wearing fur coats over their negligees, doing the laundry in the bidet, and getting served Champagne by an intern.

"Cohabitation with the Countess was very interesting," Sonja told PEOPLE at the RHONY premiere. "We raided the wine cellar. We fell up the stairs, we fell down the stairs. We brought the luggage up in the elevator, and then we eventually brought the luggage down in the elevator, because she got engaged."

As you saw in the above clip, Sonja and Luann got along swimmingly as roomies, even if Luann wasn't allowed to bring any men back to Sonja's daughter's room (where she was staying) and the heat was kept low inside the townhouse due to the high cost of keeping the whole place warm, according to PEOPLE. "Luann and I feel like we're a married couple; we don't have to talk when we're together," Sonja said. 

However, there was one person who wasn't so thrilled about Sonja and Luann shacking up together: their castmate Ramona, who Sonja said was jealous of their cohabitation. "It's just that Ramona gets a little annoyed, because Ramona and I are very close and she gets very possessive," Sonja explained. 

But Ramona told PEOPLE why she thinks Sonja and Luann's living arrangement worked so well."I don't think they were ever home together at night," she said.
