Bruce Willis' daughter shares touching throwback photo celebrating dad's birthday

Rumer Willis will always be her dad's little girl, but during her dad's birthday, she jokingly said that she used to try to be her father's son.

With Bruce Willis having five daughters, he must always wonder what it would be like if he had a son. The singer and actress however tried to reassure her father's fans that she was trying to fit the son role while she was growing up.

"Happy Birthday Papa. I love you to the moon and back. (Here I am pictured trying to be your son....)"

In the photograph, Rumer was still a little girl riding her father's shoulders as they posed outdoors. Her hair was cropped short and held Bruce's cap in her hand. True to what she was trying to say, she did look like she could be mistaken for a boy with how she looked, except those close to them know that she will always be daddy's little girl.

Meanwhile, Bruce sported a green, red, and white checkered shirt, with several buttons undone over his chest as he posed on a rock.

Rumer is Willis' firstborn child with his first wife Demi Moore, who she was married to from 1987 until 2000.

Bruce was Demi's second husband, and they had two daughters after Rumer, 26-year-old Scout and 24-year-old Tallulah.

After her divorce from Bruce, Demi was married to third husbamd Ashton Kuthcer, 16 years her junior from 2005-2013.

Meanwhile, Bruce has been married to his second wife Emma Heming since 2009. The two of them have two daughters, Mable, 5, and Evelyn, 3.

His latest film release is 'Death Wish', directed by Eli Roth, who played 'Bear Jew' Donny Donowitz in Quentin Tarantino's 'Inglorious Bastards'.
