Sonja Morgan’s internship program is officially closed.

The Real Housewives of New York City star became famous for keeping a rotating roster of interns coming in and out of her Manhattan townhouse on the Bravo hit, but now she says she’s done with them.

“Oh, you know, I really enjoyed my experience with the interns and it was gratifying,” Sonja tells ET. “I needed them, they needed me. But, once I was out of the Chapter 11 reorganization and I had my bank accounts back, and I could -- I can't! It's a lot of work. It's exhausting to be side-by-side with a student all day. You have to check their work and critique.”

Sonja and co-star Dorinda Medley stopped by the ET studios for a Facebook Live chat about season nine of RHONY.

“It’s much more complicated than you think,” Dorinda says of Sonja’s internship program. “There’s a lot of legal things.”

“They don’t work autonomously,” Sonja notes. “It’s a side-by-side [thing].”

Sonja admits it became exhausting to train new people all the time, and she simply doesn’t have the energy to do it. Now, she has a full-time assistant, Connor.

“I have a great assistant now,” she says. “I'm in a different place now, too. I'm not in flight or fight every day. Now, I wanna, you know, collapse and take stock and just relax. I want to breathe now.”

The Real Housewives of New York City airs Wednesdays at 9 p.m. ET. Check out what the ladies’ co-star, Ramona Singer, had to say about the new season in the video below.
