Pete Wentz Welcomes Baby Boy
Saint Lazslo is the Fall Out Boy bassist's second son.
"Mom and baby are happy and healthy," Wentz's rep told People. "They are thrilled at the addition to the family and Bronx is over the moon to be a big brother."
Wentz has been busy relaunching his Decaydence label as DCD2 and promoting last year's Fall Out Boy comeback album and single.
