"I'm not pregnant," she told Ellen between laughs. "We got an IUD. Nothing's gonna get in that uterus."

Jessica, who was pregnant the last two times she appeared on the daytime talk show, went on to explain why daughter Maxwell, 5, and son Ace, 3, won't be getting a little sibling.

"I have two beautiful children, and I'm not having a third," the 36-year-old added. "They’re too cute … you can't top that."

Recently, Jessica was called out by mommy shamers after she was accused of letting her daughter pose like a "Playboy model" during her mermaid-themed birthday party.

In the controversial Instagram photo, Maxwell is wearing a mermaid tail and shell bikini top as she poses with her hand on her hip and a tiny pout — just like her famous mama.

"She's 5. Put some clothes on her. good grief," one follower wrote, while another said, "Kinda sad seeing a 5-year-old posing like that…"

Previously, the singer was bashed for captioning a photo of her little girl with the sexually charged lyrics "My milkshake brings all the boys to the yard and they're like it's better than yours," which many followers deemed inappropriate due to her young age.

However, Jessica, who also revealed she is working on new music, didn't seem too worried about the criticism.

"That's how I started; that's always [been] one of my biggest passions in the world," she told The Today Show. "I love to use my voice."

She continued, "Then I'm down in my basement recording. I'm sure my kids will completely take over."
