Rumer Willis Splits from Baby’s Father, Gives Update on Dad Bruce Willis

Taking to her Instagram Stories for an AMA (Ask Me Anything) this week, Willis — the 36-year-old daughter of Bruce Willis and Demi Moore — was first asked whether she and Derek Richard Thomas were “still a couple.” The pair share 16-month-old daughter Louetta.

“Nope. I am single momming it and coparenting,” she replied. “I’m so grateful for Lou. She is the best thin in my life and I’m forever grateful I was able to have the time in that relationship for her to come into my life.”

At this time, it’s unclear when the pair — who started dating in 2022 and revealed that same December they were expecting a child together — split.

The last post they did on Instagram together was for Father’s Day back in June, where Rumer wrote, “Derek, Lou is so lucky to have a papa that loves her so much. I am so grateful she has a dad that encourages and helps to cultivate her sense of wonder and play and teaches her it’s okay to get dirty and run barefoot in the grass. Happy Fathers Day.”

During the same AMA, Willis was also asked, “How’s your dad doing? Sending love to all you guys.”

She replied with a photo of her holding her father Bruce’s hand, adding, “He is great. I love him so much. Thank you.”

Willis was diagnosed with frontotemporal dementia (FTD) in March of 2020, and as a byproduct struggled with aphasia, a brain-mediated inability to speak or to understand speech.

The family first announced that he was retiring from acting in March of 2022 due to a rare form of aphasia. The following February, they revealed his FTD diagnosis.
