Jennifer Hudson, 27, welcomed son David Daniel Otunga Jr. on Monday, her rep confirms to PEOPLE.
"The baby is beautiful and perfect," says Hudson's rep Lisa Kasteler. "His parents are ecstatic."
David weighed 7 lbs., 14 oz., at birth and is the first child for Hudson and her fiancé David Otunga. The couple kept the sex of the baby a delivery surprise.
Throughout the duration of her pregnancy, Hudson refused to confirm or deny that she was an expectant mother, instead allowing her burgeoning bump to speak for itself. As late as last month, she took the stage in Los Angeles to perform "Will You Be There" at the public memorial for Michael Jackson.
Her relative silence didn't stop colleagues from sending their well-wishes, however. Anika Noni Rose predicted in June that her Dreamgirls costar would go on to be a phenomenal mother, telling PEOPLE that David Jr. would be "much loved."
