Helen Mirren brought the most adorable date to the premiere of “Shazam! Fury of the Gods” Tuesday night.

The Oscar winner turned the red carpet into a family affair when she arrived with her step-grandson Basil as her plus-one.

The 77-year-old stunned in a black lace gown with a plunging neckline and long sleeves while posing for photos with the little one and holding his hand.

Mirren’s long platinum hair was styled in loose curls over one shoulder, and she secured the ‘do with a black headband.

The “Queen” actress completed the glamorous look with glittering silver drop earrings, two massive sparklers on her hand and a slick of pink lipstick.

Her guest, who is believed to be the son of Mirren’s youngest stepson, Alexander Hackford, looked dapper in a blue button-up shirt with dark wash jeans and black sneakers.

The Golden Globe winner is also the step-grandmother to Wayne and Buck, her husband Terry Hackford’s late son Rio’s children.

The 51-year-old died in April 2022 after battling uveal melanoma, a rare and aggressive form of cancer.

Mirren and Taylor said in a statement to People at the time that they were “both inspired by” Rio’s life and “heartbroken by his loss.”

The couple, who wed in 1997, continued, “He shared his life’s journey with so many who now mourn him, and at the same time, celebrate their fortune in knowing him.”

Terry welcomed Rio in 1970 with his ex-wife Georgie Lowres, followed by Alexander with Lynne Littman in 1979.

Mirren and Alexander’s son were all smiles celebrating the new D.C. movie, which is out Friday.

While playing villain Hespera in “Shazam! Fury of the Gods,” Mirren used a “different psychology,” she told the New York Times Wednesday.

“You don’t have to deal with normal human psychology, which is great,” she explained. “We didn’t have to consider ‘Why is this villain doing this?'”
