The Hollywood icon also has three other daughters, Rumer Willis, 24, Scout LaRue Willis, 22, and Tallulah Belle Willis, 19, with his ex-wife Demi Moore and he insists he is proud of all his girls.
He added: "I'm just very proud of all of my daughters. It's all good, I haven't found a time yet that is bad. I get to learn a lot more about women than most men do because it's just me, there's me and 20 women around me."
Bruce's home life is seemingly a world away from the tough-man image he is famed for in his action movies such as Die Hard, as he is bossed around by his daughters and wife.
He said: "You would think that sometimes they'd let me be in charge but just briefly, just for mere moments really."
Bruce has had a busy year following the release of A Good Day to Die Hard and GI Joe: Retaliation, but now that his latest film Red 2 has wrapped and is out he intends to enjoy some downtime with his family.
Bruce explained: "I'm unemployed right now and just being a dad, you know, I'm gonna change some nappies."
