Rockwell's Journey Begins

Back in August 2015, Lucy welcomed Rockwell into her life via a surrogate, embracing motherhood as a single mom. The announcement came with a heartwarming Instagram post: "Introducing the new little man in my life, my son Rockwell Lloyd Liu. In [love]!" Alongside the post was a sweet photo of Lucy holding her newborn son. It was a moment that touched the hearts of many fans around the world.

Lucy Keeps Rockwell’s Face Private

While Lucy occasionally shares glimpses of her life with Rockwell, she is incredibly protective of his privacy. Fans are treated to delightful moments of the pair at places like the museum and the zoo in New York City, where they reside. However, Lucy rarely shows his face in photos, a choice that many admire for its thoughtfulness and respect for her son's privacy.

First Birthday Memories

Lucy marked Rockwell's first birthday with a similar outpouring of love. "Happy 1st birthday to my little love Rockwell! This has been the most incredible year of new adventures and endless fun. Giant thanks for everyone's generosity," she wrote at the time. It’s clear that Lucy cherishes every moment with her son, and she's grateful for the support and love from her fans and friends alike.

Lucy on Expanding Her Family

In an exclusive interview with Closer Weekly, Lucy opened up about the possibility of adding another child to her family. “I don’t know. For me, it’s just about the present moment,” she explained. “So I’d like to just enjoy before I start to [look into the future] about anything else. Because I think sometimes it can get too overwhelming and then you’re like, 'Oh my god!' Because you don’t really get to be where you are, you’re just too busy planning for the next thing.” Fans are certainly hoping that Rockwell might get a cute little sibling sooner rather than later!
