Pete Wentz and Ashlee Simpson are seen taking their son, Bronx Mowgli, catch a departing flight to London.

Pete Wentz and Ashlee Simpson are spotted arriving at LAX airport in Los Angeles on Tuesday, March 3. The happy parents also take their 3-month-old son, Bronx Mowgli, catch a departing flight to London.

This is the first time Pete and Ashlee are photographed taking their baby boy out in public since his Christmas-day photo debut. In these pictures, Bronx looks cute and adorable.

Pete Wentz recently shared his secret to putting his son to sleep. "To get our son to sleep we play him Bob Dylan's 'You Belong To Me'. Or a little Sinatra," he told Daily Mail. "My boy's probably the last person in the world to appreciate my singing voice. Although I wrote a lullaby especially for him - you'll find it on our new album if you look hard enough - it's a hidden track. We had so much fun doing it I'm going to put out an album of songs for children."
