Oscar de la Hoya and Millie Corretjer have welcomed their second child together, Nina Lauren Nenitte de la Hoya, born Saturday in San Juan, Puerto Rico, the couple have announced.

The girl arrived at 4:36 p.m. local time, weighing 7 lbs., 13 oz., and measuring 20.5".

"We are so excited and blessed with the new addition to our family!" boxing champ de la Hoya said in a statement.

The pregnancy was first announced in May – an hour after de La Hoya lost a major match in Las Vegas to "Pretty Boy" Floyd Mayweather.

Nina is De La Hoya's fourth child and Corretjer's second. The couple welcomed a son, Oscar Gabriel, on Dec. 29, 2005.

De La Hoya, 34, and Corretjer, a 33-year-old pop singer, were married Oct. 5, 2001. The couple met in 2000, when both were signed to the same record label. (De La Hoya's debut CD that year earned a Grammy nod.)

The boxer has two other children from previous relationships: Jacob and Atiana. Atiana's mother is former Dancing with the Stars contestant Shanna Moakler.
