One day at a time, Rita Moreno has seen a change in George Lopez.

Ahead of his guest appearance on the 63-year-old’s sitcom “Lopez vs Lopez,” the 92-year-old star revealed that the comedian “changed quite a bit” since they worked together on his series “The George Lopez Show” in 2007.

“He’s really lightened up,” Moreno told People on Friday, adding that Lopez is “funnier” than ever.

The Oscar winner first played the comedian’s mother in “The George Lopez Show.” Now she portrays the spirit of George’s fictional deceased grandmother, Dolores, in “Lopez vs. Lopez.”

Moreno continued, “He’s gotten kind of cute and cuddly. I know it’s hard to think of George as a cuddly person, but I kept leaning into him, and he put his arm around me.”

The actress added that the pair are “very affectionate together,” and Lopez has become “a pretty nice guy” since they first teamed up. In fact, after filming the NBC sitcom alongside Lopez’s daughter and co-star, Mayan, the actor took the entire cast to dinner at a “wonderful” Mexican restaurant.

“He was never a sweet person, but he is now, and I’m very fond of him,” Moreno shared.

The “80 for Brady” star first met Mayan, 28, on the set of the early aughts commission, and when the two reunited on “Lopez vs Lopez,” the writer confided in Moreno about her past estrangement with her father.

She recalls giving the young star “motherly advice.”

Noting that Mayan is now “more confident” in her acting abilities, Moreno added, “She’s also funny. You know, I think it’s in the genes.”

Moreno also took a moment to talk about reuniting with her on-screen family, this time as Dolores.

She describes her character as a “mean, horrible, bitchy grandmother” who was “nasty” to George when she was alive.

“I loved why she comes back from the dead,” Moreno shared NBC News 2023. “She came roaring back, nasty as ever, in that family, demanding respect.”

“The idea really tickled my fancy,” she added, sharing that the dynamic between Dolores and George is comedic but has a serious undertone.

“Obviously I love the ending, which we don’t want to give away,” Moreno admitted. “That’s what really won me over. I thought it was so funny.”

Dolores returns during the show’s Día de los Muertos episode, which airs on NBC on Friday, October 25.
