SPOT/AKM-GSIIt looks like somebody's already in the Halloween spirit!
Pete Wentz sported a skeleton shirt while happily taking his 4-year-old son, Bronx, out in search of some gorgeous gourds at the Mr. Bones Pumpkin Patch in West Hollywood, Calif., on Thursday.
The place has become a pretty popular destination this time of year for famous folks.
The sighting here comes just three days after Olivier Martinez was spotted with wife Halle Berry's daughter Nahla following the birth of the couple's son, Maceo.
Bronx's mom, of course, is Ashlee Simpson. She and Wentz were married for three years before calling it quits in 2011.
