In December 2023, People reported that Robert was engaged to Suki Waterhouse. He and the Daisy Jones & the Six actress were first linked more than five years earlier, in July 2018.

“They are engaged. They both want to be married. It’s important for them,” a source told People at the time.

That happy update came one month after another. In November 2023, Suki — who’s also known for her roles in the films The Bad Batch and Assasination Nation — revealed that she was pregnant.

The source noted that Robert “can’t wait to be a dad,” adding: “He’s so ready. His relationship with Suki is incredible. He feels very lucky.”
