Kung Fu Kenny is trying a different type of combat sport.

TMZ has footage of new dad Kendrick Lamar sparring in a Northridge, California.

This clip is from earlier this year, and TMZ's source said K.Dot was able to go about four rounds and looked sharp.  It's not clear if Kendrick is training for anything particular, but the gym is off the beaten path so whatever he's doing he wants to keep it on the low.

Perhaps he will incorporate his new skill into his new album, which should be coming fairly soon based on his traditional album release pattern.
