Amber Heard is a mom!

The actress, 35, is celebrating the birth of a baby girl — months after ex-husband Johnny Depp lost his libel case involving her.

A source exclusively told Page Six on Thursday that Heard is “beyond in love” with her daughter, Oonagh Paige, whom she named after her late mom, Paige.

Oonagh was born on April 8 with the help of a surrogate after Heard was told she would never be able to carry her own baby, friends revealed.

A source who knows the star told us: “Oonagh is absolutely gorgeous, and Amber is besotted. She always knew that she wanted to be a mom, and this is her greatest wish come true. She’s so grateful to the wonderful woman who helped bring Oonagh into her life.

“The most important thing for Amber is that she’s open about Oonagh’s birth,” the source continued. “There are so many women who feel they can’t talk about their fertility and are worried and embarrassed; Amber wants them to feel supported and realize that there are a multitude of ways to have a baby even if you have fertility issues.”

Heard confirmed the news herself on Thursday via Instagram, where she shared a photo of herself with the infant.

“I’m so excited to share this news with you. Four years ago, I decided I wanted to have a child. I wanted to do it on my own terms,” she wrote. “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. I hope we arrive at a point in which it’s normalized to not want a ring in order to have a crib.”

She added, “A part of me wants to uphold that my private life is none of anyone’s business. I also get that the nature of my job compels me to take control of this. My daughter was born on April 8, 2021. Her name is Oonagh Paige Heard. She’s the beginning of the rest of my life.”

Heard is currently in a relationship with cinematographer Bianca Butti, whom she has been dating since January 2020, but she made the decision to have a baby on her own some time ago and is “proud” to be Oonagh’s sole legal parent, we’re told.

The birth of Heard’s baby is particularly poignant, friends say, as she lost her own mom in May 2020 at the age of 63, saying at the time that she was “heartbroken and devastated beyond belief.”

She called Paige “the most beautiful woman I had ever known” in an Instagram post, adding: “It’s hard to imagine and even more difficult to say but I feel truly lucky to have been her daughter and been given the gift of having the light she shone on everyone, fall on me for nearly 34 years.”

Heard then thanked her family and friends for helping her and her sister, Whitney, during the “unbelievably painful time.”

The star’s mom’s death came just weeks before she faced Depp, 58, in London’s High Court in a three-week trial in July 2020.
