Actress Jessica Alba, who is expecting third child with husband and film producer Cash Warren, says she wont have more children and is happy with her brood.

Asked whether she is planning to have more children after the third one, Alba told eonline.com: "Last one."

The soon-to-be-born child will join the couple's two daughters -- Honor and Haven.

Alba started dating the son of actor Michael Warren after meeting him on the set of "Fantastic Four" in 2004. They got married in 2008.

The actress said she is currently enjoying the balance between her personal and professional lives.

"A happy work place actually makes for a healthier person and healthier children. If you work five hours a day but you hate your job, your attitude when you come home and what that imposes on your kids' outlook and their life and their relationship with them, it actually really affects it," she said.

"But if you're happy -- even if you come home late and you're working long hours -- if they see that you're happy and you're in a good mood and you're present with them that's way better than you spending 10 hours a day with them in misery," she added.
