Matthew McConaughey's son, Levi, may be just 14 months old, but he's already giving his parents a run for their money.
In a new letter posted on his official Web site on Wednesday, the actor revealed that little Levi is tearing up the house as he waits for his mom – Matthew's girlfriend Camila Alves – to give birth to his sibling.
"Levi is doing terrific waiting for his little bro or sis," Matthew wrote. "We had to super child proof the new house because he's motoring around like [Jamaican sprinter] Usain Bolt and eatin' like [Japanese professional eater Takeru] Kobayashi. Camila and I can barely keep up."
Matthew said his son has earned a nickname for his voracious toddler appetite.
"We call him the fruit bandit 'cause if there's fruit out, he's on it, takin' it and eatin' it," the actor wrote. "He's getting bigger, more fun, smarter and craftier by the day."
Also getting bigger is Camila's blooming belly, although Matthew said they haven't learned their impending arrival's sex.
"My lady Camila and I got another baby on the way," he wrote. "Not sure if it's a boy or a girl but we have our instincts."
