While most second graders are perfecting their reading skills, 8-year-old MattyB is fine-tuning his rap method. In a funny-cute new video, the 4-foot tall boy tackles the Black Eyed Peas hit, 'Just Can't Get Enough.'

The mini-Bieber has impressive flow, and you can tell it isn't his first time up to bat. In fact, MattyB boasts an incredible 50 million YouTube views and 200,000 subscribers to his page. "I'm learning how to rap and I'm excited about starting my career in the music industry here on YouTube through my music videos," the pint-size rapper says on his site.

To date, the youngster has spun rhymes over songs by big-name artists like Rihanna, Bruno Mars, Lady Gaga, Eminem, and -- of course -- Justin Bieber. And, on top of his talent and street cred, he's actually hilarious.

We totally dig this spitfire version of the Black Eyed Peas' popular song ... Maybe even more than the BEP's popular song. Best of all, we love that MattyB keeps it real, and he's not rapping about big women and fast cars -- rather, grade school girls and toy cars. Keep it up, short stack!
