"La Bamba" star, Lou Diamond Phillips, 45, and wife Yvonne Marie welcomed their new baby daughter Oct. 9.

However, the couple waited until now before announcing the birth.

Indigo Sanara Phillips weighed 6 lbs. 11 oz. and is the first child for the couple. 

Lou already has 10 year old twins, Grace and Isabella, and 8-year-old Lili from a previous marriage.

Wow, a fourth girl! I hope he's happy regardless!

Congrats, Lou and Yvonne!
