Jon Furniss/WireImage.comMatt Damon has that girl group he's always wanted.
The 37-year-old actor welcomed his second daughter with wife Luciana today, Damon's publicist confirms to E! News.
"Matt and Lucy Damon had a baby girl named Gia Zavala on Wednesday, Aug. 20. Everyone's doing great," rep Jennifer Allen said.
The new addition joins sister Isabella, 2, and half-sister Alexia, 10, Luciana's daughter from a previous relationship, in the Bourne Ultimatum star's ultrafeminine household.
"I'm so outnumbered down here, it's crazy," Damon joked to USA Today recently.
People's reigning Sexiest Man Alive—who had to relinquish his crown for a bit while filming Steven Soderbergh's The Informant—swapped vows with his Argentinian-born missus in December 2005.
