Is That Cooper Flagg’s Grandmother in the Bingo Commercial?
A Closer Look at the Heartwarming AT&T Spot
(By Carmichael Phillip)
Putting a Face to the “Mammy”
In AT&T’s 2025 “March Madness: Bingo” commercial, Duke basketball phenom Cooper Flagg excitedly yells “B-2! Bingo!” before a warm, familiar voice reminds him to go shake hands with the other players. That voice belongs to his grandmother — or at least, an actor portraying her in a sweet cameo.
The question many viewers have asked: Is that really Cooper Flagg’s real grandmother in the ad? While AT&T and Flagg have not publicly confirmed whether the woman is his actual grandmother or an actress, several credible sources and interviews suggest that she is indeed meant to represent his real grandmother — and perhaps even is her.
What the Commercial Shows
In the commercial — which was released as part of AT&T’s March Madness campaign — Flagg plays bingo in a hall. When he stands and proclaims “B-2! Bingo!” in enthusiastic celebration, a woman, referred to by Flagg as “mammy,” congratulates him and reminds him to show good sportsmanship.
Her words are:
“Shake their hands.”
And Flagg replies:
“Yes, mammy.”
This interaction anchors the emotional core of the ad — it’s not just about bingo or competition, but about family, respect, and humility.
What Has Been Reported About Her Identity
Several media reports and interviews support the idea that the woman is Flagg’s actual grandmother, or at least that she is meant to be his real-life grandmother in the ad:
According to On3, Cooper’s head coach Jon Scheyer said he saw Flagg’s “mammy (grandmother)” in the spot, calling her cameo “one of the highlights.”
90minSport also describes her appearance as a “heartwarming cameo” by his grandmother, noting how the moment brings familial warmth to the ad.
The iSpot listing for the ad simply credits “Cooper Flagg … Athlete” among the actors, but does not explicitly identify the woman.
Given this mix of sources, many believe that AT&T intentionally cast Flagg’s real grandmother (or someone very close to her) to give the commercial a genuine, personal touch.
Why This “Grandma” Role Matters in the Ad
Whether she’s Flagg’s actual grandmother or an actress playing the part, her presence serves several important purposes in the campaign:
Authenticity & Emotional Resonance
The grandmother’s role adds warmth to the commercial. It transforms what could be a purely hype-driven sports spot into something deeply human. For many viewers, the family moment feels real, not staged — which strengthens the connection to Flagg’s brand and AT&T’s message.
Respect & Sportsmanship
By telling Cooper to shake hands, she emphasizes humility and respect — values that many associate with basketball legends. This small detail paints Flagg not just as a talented athlete, but as someone raised with good character.
Relatability During March Madness
Fans watching March Madness often play bingo with their friends and family. Including a grandmother figure playing along ties into that tradition, making the ad more relatable to a broader audience.
What Fans and Media Are Saying
The response from fans and media alike has been largely positive. Many have described the grandma cameo as memorable and touching. For example:
On3 praised Scheyer’s comment on the “great acting” in the ad and highlighted the “mammy” moment as charming.
90minSport noted that her appearance adds to Flagg’s marketability — not just as a future NBA star, but as a young man with strong family ties.
Some fans have speculated whether AT&T deliberately used his real grandmother to give the spot more authenticity, and the media coverage seems to lean toward “yes, they did.”
Is There Any Official Confirmation?
As of now, neither AT&T nor Cooper Flagg has publicly released a statement explicitly confirming whether the woman is his biological grandmother. The casting credits for the ad (as listed on iSpot) do not name her, which leaves things a bit ambiguous.
However, given how several interviews and third-party reports refer to her as his grandmother, it seems likely that AT&T, Flagg, or those close to him are comfortable letting the public interpret her as real family.
The Bigger Picture: Why This Cameo is Smart for AT&T
Including this grandmother figure (real or implied) is more than just a sweet storytelling choice — it’s a savvy marketing move for AT&T:
Brand Values Alignment: AT&T’s tagline for the ad, “Connecting Changes Everything,” isn’t just about network connectivity — it’s about connecting people, generations, and moments. The intergenerational bond in the commercial plays directly into that message.
Emotional Storytelling: In a sea of typical March Madness ads, this one stands out by combining humor, competition, and family love.
Athlete Branding: For Cooper Flagg, the cameo deepens his personal brand. It shows him as not just a young star, but a family-oriented person — a narrative that sponsors and fans both appreciate.
What’s Next for Cooper Flagg’s Commercial Career?
This bingo ad isn’t Cooper Flagg’s first foray into advertising — and likely not his last. Given his rising stardom, his endorsements and media appearances are expected to grow.
If AT&T’s campaign continues, they may even explore more family-themed spots that further humanize Flagg and reinforce their message of connection. And as his career progresses, new brands will probably want to tap into his appeal — especially if that appeal includes touching, personal moments like this one.
Bottom Line
Yes, many credible sources identify the woman in the AT&T bingo commercial as Cooper Flagg’s real grandmother (or at least refer to her as “mammy”).
There’s no publicly available casting sheet from AT&T naming her explicitly, which leaves a bit of mystery.
Whether she is biologically related or simply cast to embody his grandmother, the emotional impact of her cameo is very real — and very effective from a storytelling and branding standpoint.
