Holmes has previously expressed her desire to protect her daughter from negative media coverage

Amber Heard is expanding her family.

The Aquaman actress, 38, is expecting her second baby, PEOPLE can exclusively confirm. A spokesperson for Heard says, “It is still quite early in the pregnancy, so you will appreciate that we do not want to go into much detail at this stage. Suffice to say that Amber is delighted both for herself and Oonagh Paige.”

Heard is already mom to 3½-year-old daughter Oonagh Paige, whom she welcomed on April 8, 2021. When she revealed the news of Oonagh three months after her birth, Heard wrote on Instagram that she had “decided I wanted to have a child” four years prior and “wanted to do it on my own terms.”

“I now appreciate how radical it is for us as women to think about one of the most fundamental parts of our destinies in this way,” she wrote at the time. “I hope we arrive at a point in which it’s normalized to not want a ring in order to have a crib.”

Since then, Heard has shared periodic updates about Oonagh and motherhood, including posts calling herself “just the mom and the dad” as well as a “multitasking mama.”

Heard was previously married to Johnny Depp, with whom she was embroiled in a highly publicized, contentious defamation trial in Virginia during the summer of 2022.

After that legal battle, the actress moved overseas to live a quieter life in Madrid, Spain.

With the trial behind her, Heard told NBC News’ Savannah Guthrie in a June 2022 interview after the verdict that she was looking forward to focusing on her family: “I get to be a mom, like, full time, you know? Where I’m not having to juggle calls with lawyers.”

Sources told PEOPLE last year that the actress’ decision to relocate abroad after the “chaos” and attention of the trial became overwhelming.

“The trial was beyond stressful, and she wanted to start fresh,” said one source at the time, adding that she now “has new energy and is focused on things that she loves.” Added another source: “She’s independent and smart. She needs to heal.”

Later in 2023, director Conor Allyn, who worked with Heard on the thriller In the Fire, told PEOPLE the star was “living her best life in Spain with her daughter and just finding happiness in that way.” The filmmaker added that Heard is “such a dedicated mom” and “really good about making the time” for Oonagh.
