Like many new parents,Eva Longoriavowed she’d be a low-key mom. But the joy of sonSantiago Enrique‘s approaching 1-year birthday has gotten the best of her.

“I swore I wasn’t going to be that mom andhave a crazy big birthday partybut cut to now — it’s bigger than our wedding,” Longoria told PEOPLE on Monday night in Miami, during the premiere of her new ABC showGrand Hotelat the iconic Fontainebleau Hotel (where the pilot was filmed).

She goes on to joke, “It will be black-tie optional. But we’re doing his baptism and his birthday at the same time — that’s why it’s so big.”

Longoria’s little guy actually attended the premiere himself, as “he never misses a party,” proclaims the proud mom, 44.

During the screening, the star and her husbandJosé “Pepe” Bastónstood quietly in the back of the ballroom, holding their son while he played with a rattle and cheered on the episode with his own coos and giggles.

Longoria clearly takes caretaking very seriously — both for herself and the world as a whole. As one of thefounders of the Time’s Up movement, she sees both progress that has been made and what still needs to be accomplished.

“The thing we are most successful with at Time’s Up is having a global conversation about it. We made the conversation at the forefront of every country, every workplace, across all industries,” she says of their initial efforts.

“The fact that we pulled that out of the dark, this thing that everywoman experiences in her life — this harassment,” Longoria adds.
