Harry Mack has achieved a certain amount of Internet fame for freestyling around LA.

He just got a huge cosign from none other than Kendrick Lamar.

During K.Dot's visit to Power 106’s The Cruz Show he was introduced to Mack.

Af first Lamar was polite -- like a superstar would be to a fan. But then Mack started freestyling and things changed.

Mack went over the beat to Mobb Deep’s 'Survival Of The Fittest' and effortlessly incorporated any word Lamar threw out into his freestyle.

Kendrick was impressed.

"I'm great in your eyes, but you're great in my eyes because you inspire me," Kendrick told Mack. "When I see that hunger, it runs me right back to the lab. It gets me back on my pen. So we inspire each other man, just know that. '
