Leakes, who can currently be seen in the BET+ reality show College Hill: Celebrity Edition, opened up about how her relationship with Sioh has helped her after she lost husband Gregg to colon cancer last September.
"I can't say [Nyonisela] hasn't helped me put a smile on my face," Leakes, 54, told Extra.
She added that to find joy, "You have to be willing to be happy, and you have to make a lot of changes within yourself."
Leakes was joined by Lamar Odom, Ray J, Stacey Dash, Slim Thug, Big Freedia, DreamDoll and India Love in filming College Hill: Celebrity Edition, which follows the stars as they returned to school and lived together at Texas Southern University, one of the United States' historically Black colleges and universities (HBCUs).
"I went to an HBCU, I love Houston, so I said, 'Let's go back and really see what's happening,'" Leakes explained of her reason for participating in the series.
That said, she did admit, "I wasn't super excited about moving into a house with a bunch of celebrities because I never lived with celebrities before, and I know celebrities are divas."
As for whether cohabitating with celebrities or returning to college was more challenging, Leakes said, "Definitely going back to school. We are sitting in class with young college students, so they know everything. We don't know anything."

In one video, she called this year's ceremony "one of the best BET Awards they have had in a very long time."
However, Leakes also did acknowledge that she wasn't a huge fan of how her and Sioh's ensembles looked in photos from the carpet.
"You know, we wore blue. I don't like how our pictures photographed at all. Sometimes it be like that, child. I don't care. We will shoot again today," she said with a giggle.

The couple announced their budding romance in December of 2021, when a source close to the Bravo star told PEOPLE she is "very happy right now."
Leakes previously confirmed to The Shade Room that her husband Gregg gave her this blessing before he passed: "His words to me were 'be happy, keep smiling and he who finds you, has found a good one.'"
