Good wishes flooded Jessica Alba's Facebook page after the glamorous actress announced on Sunday that she gave birth to a baby girl with husband Cash Warren.

"Cash and I are so excited to announce the birth of our daughter, Haven Garner Warren. She was born on Saturday, weighed 7 lbs, and was 19 inches long. Healthy and happy! Big Sister Honor couldn't be more excited about the new addition to our family," the 30-year-old "Fantastic Four" actress wrote. "Thank you for all of your support during my pregnancy. It means the world to me."

It was in February this year that Alba announced her latest pregnancy via Facebook and Twitter.

"Can't tell you how much the positive tweets mean... Smiles from ear to ear. lots of love back at cha," hubby Warren tweeted at the time.

Alba also turned to her Twitter account to thank her fans for well wishes. She wrote: "And again I can't thank you enough for all of the wonderful messages you sent me today."

During the "Spy Kids 4" premiere a couple of weeks ago, Alba said Haven may be the last child for the couple. "I really can't imagine having more than this, more than what's happening right now," E! Online quoted Alba as saying. "Kids are a lot of work, and at the end of a pregnancy, it's sort of like you can't really imagine having more. But we'll see."

Just a few days before she gave birth to Haven, Alba shared a little update.

"I've banned my loving husband from cooking a half a pack of bacon every morning and ordering or buying five desserts for dinner every night," Alba wrote in her blog on iVillage. "I'm doing prenatal yoga and taking 30-minute walks through my last trimester, which is more than I did with Honor."

Meanwhile, good wishes from her fans are flooding Twitter as well.

"Congratulations on your new baby girl! @JessicaAlba," Marissa Anita tweeted.

"Aww Jessica Alba and cash had a baby girl. I'll prob. have to get them a congrats card," another fan named Danielle tweeted.
