Pete Wentz and baby boy Bronx Mowgli were out and about in Los Angeles Tuesday, but not together!

While Pete walked the streets, Bronx hit up the park with his nanny. He looks too cute!

Like his hat says, Pete still seems to be a wild one: he isn't wearing his wedding band, though he and wife Ashlee Simpson have been spotted out together since they filed for divorce.
