And the two-time Golden Globe nominee is already celebrating another important life, as she basks in new motherhood.
She gave another glimpse at newborn son Ever Leo, as she posted Saturday to Instagram, celebrating her 34th birthday at home with her favorite guys.
The 34-year-old teased her baby boy's fuzzy head, as she carried him in her arms with her back to the camera, captioning the photo: '34'
She stood over a beautiful flower arrangement and a chocolate cake, which read: 'Happy Birthday Mom!'
Lea and Zandy, 37, welcomed their son last Thursday, August 20, after announcing their pregnancy back in May.
A source told People: 'Everyone’s happy and healthy, and they're extremely grateful. He's been an easy baby so far.'
The proud parents later gave a first glimpse at their new addition in a black-and-white photo of their hands holding his tiny feet.
She hinted at the baby's name in the caption, writing: 'ForEver grateful for this true blessing.'
The Glee actress was first romantically linked to Zandy back in July of 2017, tying the knot last March in Napa.
She's been showing off her baby bump to her 6.5million Instagram followers, while enjoying her pregnancy in quarantine.
Lea broke the news back in May, sharing a photo of herself cradling her bump in a blue dress, writing: 'So grateful'
