Pete Wentz's girlfriend Meagan Camper recently gave birth to a son, Saint Lazslo, in Los Angeles, making the musician father for the second time.
The representative for the 35-year-old Fall Out Boy bassist confirmed the news to People magazine and said that the pair was "thrilled" to have their first child and both baby and the model girlfriend baby momma, 25, were healthy.
Wentz's 5-year-old son Bronx with his former wife Ashlee Simpson too was "over the moon" to have a younger brother, added the rep.
Earlier, Wentz had revealed that they didn't know the sex of the baby and were planning to keep it a surprise for themselves up until the child's birth.
