Hola! USA has shared the first photo of the baby, who was born on June 19.
"We are so grateful for this beautiful blessing," Longoria, 43, told Hola!.
Together with husband Jose "Pepe" Baston, the happy couple have welcomed a beautiful baby boy.
Eva first sparked pregnancy rumours when she was photographed wearing a loose-fitting dress while on vacation in Greece in September 2017. She happily confirmed the news in December 2017.
The amazing news comes soon after Eva's 43rd birthday and after she was recently awarded a star on the Hollywood Walk of Fame.
Congratulations to the happy couple and may their beautiful baby boy be healthy and full of life!
