Chad Lowe and his girlfriend Kim Painter welcomed a daughter, Mabel Painter Lowe, on Saturday in LA.
“Everybody is healthy and happy,” the rep said.
The couple said they were “overjoyed and could not be happier,” after announcing Kim’s pregnancy in January.
Chad, 41, and Kim, a producer, first began seeing each other in 2007. Chad split from Hilary Swank in 2006.
