Roberto Hernandez married Kristy without inviting his own mother to the wedding. That decision set a clock ticking — and when it went off, it produced the most famous number in I Love a Mama’s Boy history: 99.99 percent. Here is how it happened, in order.
The Wedding Nancy Was Never Invited To
Long before Season 3, Roberto and Kristy eloped — married in secret, without Nancy in the room. Kristy was already pregnant, and Nancy never forgave either fact. She read the elopement as Kristy stealing her son away, and, according to reports, vowed to end the marriage she had not been invited to bless.
A Phone Full of Photos, and One Daughter Who Did Not Look Right
The reason arrived in the Season 3 premiere in June 2022. Roberto pulled out his phone to show his mother pictures of his two little girls. Nancy studied them and delivered her verdict: the older girl was the spitting image of Roberto, but the younger one, Kimi, looked nothing like him. Then came the suggestion, dressed up as concern: a DNA test to settle it once and for all — with an accusation hiding underneath, that Kristy had cheated.
Roberto was furious, and said so on camera: his mother had hit a new low by demanding a paternity test for his own daughter on national television.
June 26, 2022: The Night Roberto Told Kristy

Three weeks later, in the June 26, 2022 episode “How Do You Feel About Tests?”, Roberto told Kristy what his mother wanted. Kristy felt hurt and disrespected — her husband was asking her to prove her loyalty on his mother’s say-so. Roberto insisted the test would bring the family peace. Kristy saw the trap: take the test and swallow the insult, or refuse and hand Nancy proof — in her eyes — that the suspicion was justified.
She chose the test. On July 23, 2022, in the episode “It’s Mama’s Day, Honey,” Kristy and Roberto took it, much to her dismay. Fans were furious — one widely shared reaction: take the test, hand him the results along with divorce papers.

Two weeks later, in the August 7, 2022 episode “She’s That Evil,” the couple shared the results with Nancy: 99.99 percent his — about as certain as science gets. It changed nothing. Nancy reportedly asked why the result could not be 100 percent, then questioned whether the test was even authentic. The woman who had demanded proof now refused to believe the proof she got.
The Walkout That Rewrote the Family
That was when Roberto finally snapped. He demanded his mother apologize to Kristy. Nancy refused — and accused Roberto himself of doubting his daughter’s paternity. Kristy stood up, delivered the coldest line the show has ever aired — “Who is she that I have to prove to her?” — and walked out. Roberto followed his wife out the door, declaring he was choosing his wife and kids over his mom. It became the walkout that saved the marriage.
The moment puts Roberto near the top of the sons who finally picked a side — and, according to reports, the choice held: the couple later distanced themselves from Nancy, and they are still together.
According to reports, that distance has held into 2026 — the 2026 couples scorecard still counts them among the show’s survivors. Two years after the Season 4 finale, with TLC still silent on Season 5, it looks less like a wound than the boundary that saved them. Nancy got the proof she demanded and lost her son’s trust instead — so if a fifth season ever comes, should TLC bring Nancy back to the table, or has this family already given its final answer?
