Leaving their little son Bronx home with a babysitter, Ashlee Simpson and Pete Wentz were spotted out on a dinner date in West Hollywood last night (August 31).

The Fall Out Boy bassist and his “Pieces of Me” wife looked to be enjoying each other’s company as they made their way back to their car, carrying a container of leftovers for Pete’s dogs.

In related news, Wentz recently told press that his new comic book series “Fall Out Toy Works” was inspired by his son.  “I think after you have a kid, all of a sudden you want to do things that your kid can see.”

He continued, “The underlying theme of the story looks at human beings’ most essential question: Can you create artificial love?  It explores the dimensions of what love really is. Can it be designed in you? Can a robot fall in love?”
