Milla Jovovich collects weapons. The model-and-actress - who has a 21-month-old daughter Ever Gabo with her partner, director Paul W.S. Anderson - says she was never interested in traditional childhood toys and has carried her passion for martial arts and combat into her adult life.

She said: "I have so many weapons at home. It's not like I sit at home twirling knives, but I've always been into handling weapons. As a kid I liked ninja warriors, not dolls. I have some kukris. They are one-handed knives and a bit like machetes, very vicious instruments with a curved blade. They are used for hacking and I love them because they are so versatile. You can really get into the meat of an animal, slice cucumbers and kill zombies - all in one day."
