Rumer had a red one covering her brunette hair and the father-daughter duo looked so sweet.
Rumer briefly mentioned the photos in the caption which read: "Cleaning House! One of the biggest lessons I learned around self care this year is about allowing your space to be a reflection of your inner reality.
"So since the beginning of the year I have been devoting energy every day to make sure the place I live is one that feels safe, well organized, alive and full of and everything that brings me joy."

Rumer said she loves bringing in her "favourite candles, diffusers and personal photos and trinkets that mean something," and wrote she makes sure to clean everything away at the end of the day to kickstart the following with a clean slate.
She added: "Now this may seem small or trivial or something you already do, and that's cool too.
