In a sweet post on Instagram on Monday, Rebel Wilson announced that she’s officially a mama! In her post, she shared the first image of her sweet daughter and thanked her surrogate for carrying the baby as well.

“Beyond proud to announce the birth of my first child, Royce Lillian, born this past week via surrogate,” Wilson wrote on Instagram. “I can’t even describe the love I have for her, she’s a beautiful miracle!”

Wilson is currently in a romantic relationship with designer Ramona Agruma—the couple became public earlier this summer in a post where Wilson referred to Agruma as her “Disney Princess.”

In the baby announcement, Wilson thanks “everyone who has been involved” with her road to motherhood.

“This has been years in the making…but particularly wanted to thank my gorgeous surrogate who carried her and birthed her with such grace and care. Thank you for helping me start my own family, it’s an amazing gift. The BEST gift!!”

In May, Wilson told PEOPLE that she wanted to get “healthier” due to her desire to become a mom. She told the magazine that she first visited a fertility doctor in 2019, who suggested that she should lose weight if she wanted to harvest and freeze her eggs.

“I was taken aback. I thought, ‘Oh God, this guy’s so rude.’ He was right,'” she said at the time. “I was carrying around a lot of excess weight. It’s almost like I didn’t think of my own needs. I thought of a future child’s needs that really inspired me to get healthier.”

Though some scientific literature points to lower fertility in women who are overweight by outdated BMI standards, a trial published in PLOS Medicine found that women with clinically defined obesity and unexplaned infertility who lost weight before starting fertility treatments did not have a greater chance of conceiving or improved birth outcomes compared to those who didn’t lose weight.

Wilson ended her birth announcement in a way that only a smitten new parent could—acknowledging how much love there is while also recognizing how hard it is.

“I am ready to give little Roycie all the love imaginable. I am learning quickly…much respect to all the Mums out there! Proud to be in your club.”
