The 44-year-old actress welcomed 10-month-old Santiago last year.
ET's Nischelle Turner caught up with the 44-year-old actress at The Hollywood Reporter's Empowerment In Entertainment Event 2019 at Milk Studios, which honored Oprah Winfrey, and she explained why she went back on her plan not to post photos of her baby on social media. Longoria and her husband, Jose Baston, welcomed 10-month-old Santiago last year.
"It's no longer my Instagram," she quipped, referencing all her posts of Santiago. "It's so funny because before he was born my husband and I said, 'We're not going to post too much. We're going to keep that life private.' And everyday I'm like, 'I have to post this! This is so cute!'"
"Yeah, that totally went out the window," she added.
Thanks to her little one, Longoria will be celebrating her first Mother's Day this year. While the milestone is certainly exciting, she finds joy in the day-to-day life of being a mom.
"My heart is filled every day," she said. "... The joy of my son and kissing him and squeezing him and smelling him every single day. Mother's Day is everyday!"
Though she joked that she'd like "diamonds" for her very first Mother's Day gift, the real present will be time spent with Santiago.
"I don't share him very much. I hog him all the time," she admitted, before revealing her Mother's Day plans. "I'm always traveling with him. I'm actually going to be in Cannes this year with him on Mother's Day, so he'll be with me and I'll be hogging him all to my self. That's my gift. Just to be able to spend time with him."
Longoria was at Tuesday's event to support Winfrey, its first honoree, who was celebrated for creating opportunities for people of color, women, members of the LGBTQ community and others.
"Witnessing and applauding and celebrating these other women who are doing amazing things for minorities, for people of color, for LGBTQ, this really gets me inspired," Longoria said, before lavishing more praise on the 65-year-old media mogul.
"She produced with substance and continues to do that in her life, and in her interactions with people, and the world, and communities," Longoria said of Winfrey. "So, to me, that's a big lesson she taught me -- produce with purpose, everything in your life, not just a TV show, but everything. Produce your life with purpose."
