Bre Tiesi was "upset" to learn about Nick Cannon's ninth baby online, her "Selling Sunset" costar Chelsea Lazkani has claimed.

In the fourth episode of the latest season of the Netflix reality show, Lazkani told the other real estate agents about Tiesi's off-camera reaction when she discovered Cannon would be welcoming another baby with model LaNisha Cole.

Cannon's daughter with Cole, Onyx Ice, was born just three months after Tiesi gave birth to her and Cannon's son, Legendary Love, now 10 months.

Legendary Love is the eighth of Cannon's 12 children, whom he shares with six different women

"So, she pulled up her phone and she turned it to me," Lazkani said of Tiesi (per People). "It said, 'Nick Cannon welcomes child with LaNisha Cole.'"

Lazkani added that Tiesi was "very surprised" and "very upset."

"This was, like, completely a secret," she said. "Ultimately, every additional baby is time taken away from the bond that your child and their father is gonna have."

In the fifth episode, agents Chrishell Stause, Amanza Smith, and Heather Rae El Moussa then shared their thoughts about the situation.

"Obviously, Bre is sensitive about a very personal topic," said Stause, who was also present during the conversation with Lazkani and Tiesi when Tiesi found out about Cannon's ninth baby.

"She was, you know, really emotional," she added.

Smith said: "It felt like to me Chelsea was concerned that Bre's baby was going to have an absent father now or something. And then low-key blames Bre and Nick, or whatever. Because Chelsea's situation, she has a great husband. She's still married, two kids, a supportive husband. Not everybody gets that picture-perfect household."

"There's so many ways to have a family," said Stause, before Smith responded: "Nick sounds like an awesome dad."

In episode eight, Tiesi found out that Lazkani and the other agents had been talking about her relationship with Cannon behind her back, which she did not take too kindly.

"You don't need to agree with my situation; this is my situation," she said to Lazkani over dinner in Palm Springs. "I'm not going to have people in this office talk about my family. I'm not."

Tiesi then left the dinner table before finishing the night by telling agent Heather Rae El Moussa to "mind your fucking business."

"All I'm saying is respect me. Don't talk about my business. If you're going to, we're going to have a problem," said Tiesi.
