The 6-year-old has been studying martial arts with her brothers for more than a year.

Look out, Jaden Smith! Heidi Klum’s 6-year-old daughter Leni is gunning for you! OK, well, maybe not, but she is taking karate lessons!

The supermodel, 37, took baby Lou Samuel along with her to watch her oldest daughter (and her brothers Henry, 5, and Johan, 3) kick some butt at a Los Angeles dojo. Leni must be pretty good at Tae Kwon Do, based on the number of stars she has on her uniform!
