Johnny Knoxville and Naomi Nelson, his girlfriend, have welcomed a little boy named Rocko, according to the Los Angeles Times. That's awesome.

Rocko Akira Clapp, who weighed 8 lbs. and measured 20 inches, was born Sunday in Los Angeles. It is the second child for Johnny Knoxville.

His real name is Phillip John Clapp. Naomi Nelson, his girlfriend of several years, broke the news that she was pregnant earlier this year.

Johnny also has a teen daughter, Madison, with his ex-wife, Melanie Clapp. Regarding Madison, before his new son's arrival, Knoxville blogged:

"My daughter Madison has already started becoming a big sister and is helping pick out clothes, strollers and beds for her little sister or brother."

Who knew this Jackass could be such a softie?

Congratulations to Johnny Knoxville and Naomi Nelson!
