Matthew McConaughey calls his son “the fruit bandit.”

The 39-year-old actor and his partner Camila Alves, who is pregnant with their second child, came up with the unusual nickname for 14-month-old Levi because he can’t stop eating healthy foods.

Referring to 100m sprint world record holder Usain Bolt, Matthew said, “Levi is doing terrific waiting for his little bro or sis… we had to super child proof the new house because he’s motoring around like Usain Bolt—Camila and I can barely keep up. We call him the fruit bandit ‘cause if there’s fruit out, he’s on it, taking it and eating it. He’s getting bigger, more fun, smarter and craftier by the day.”

Matthew added that the whole family is excited about the new arrival, which is due at the end of the year and have started trying to guess the sex: “Above and beyond all other news, the most exciting thing is my lady Camila and I got another baby on the way… not sure if it’s a boy or girl but we have our instincts… what are you thinking?”
