Daddy duty! Pete Wentz and Bronx Mowgli out in LA

Pete Wentz was spotted carrying his 3-year-old son Bronx Mowgli after having lunch in Los Angeles. Look at Bronx’s little Ugg boots! Even though they split this year, Wentz and Ashlee Simpson celebrated their son’s birthday together on Monday.

Pete and Ashlee celebrated Bronx’s birthday at The Coop in studio City, California with Jessica Simpson and their parents, Tina and Joe Simpson.
