Clapp Your Hands: Johnny Knoxville Welcomes a Daughter!

This is the Jackass star's second child with wife Naomi and third overall

Johnny Knoxville's latest stunt: father of three.

The Jackass star and wife Naomi Nelson welcomed a daughter last week, their second child together.

And maybe as a nod to daddy's country-strong, Tennessee roots, they gave the daredevilette a name that's deeply rooted in Americana...

The little girl's name is Arlo!

"Yesterday Oct 6th Naomi, Madison, Rocko & I welcomed a brand new baby girl into our family. Her name is Arlo & mommy & baby r doing great!!" Knoxville, whose real name is Philip John Clapp, tweeted Saturday.

(The name instantly brings to mind folk singer and activist Arlo Guthrie, whose dad was "This Land Is Your Land" writer Woody Guthrie. It's also what Toni Collette named her son when he was born in April.)

Johnny and Naomi's son Rocko will be 2 in December. Madison, Knoxville's daughter with his ex-wife, is 15.
