Her father Bruce Willis is currently caught up in his parenting duties as a father to his adorable one-year-old baby girl.

But Rumer Willis wants to make sure he doesn't forget how cute she once was too.

The 24-year-old tweeted an old picture of herself on Thursday as a little girl dressed in a Minnie Mouse costume, on the same day that her father was spotted taking his youngest daughter Mabel for a walk in her stroller in New York.

Rumer - whose mother is Demi Moore - looks sweet in the snap, wearing a red dress with white polka-dots and a picture of Minnie Mouse on the front.

The little one sports large black Minnie Mouse ears and a bow in her light brown hair as she looks ahead of her while sitting next to some bushes.

She accompanied her photo with the caption: 'Take that Minnie...I look way better in those ears haha #throwbackthursday #disneyland'.

Mabel - Bruce's daughter with wife Emma Heming - was wrapped up in a cosy beige blanket as she looked around in wonder at the passersby.
