In March, Rumer took a minute to honor her dad Bruce Willis on his 69th birthday, sharing a sweet photo of Bruce with Louetta. In the shot, the actor played with Rumer's baby daughter, bending down to her level.

"With baby Lou," Rumer added across the heartwarming snap, which showed her dad smiling as he played with Louetta.

In the caption of her grid post, Rumer wrote about how much she and her little girl both love her dad. "Lou loves you so big," she concluded her post.

In November, Rumer chatted with PEOPLE about how special it's been watching her daughter become a part of her close-knit family.

"I think inherently, some of the most magical parts of myself are definitely from them," Rumer said of her parents Bruce and Demi Moore, 61.

"So I feel like that will be passed down to her," she continued. "I love watching them with her."
