The actress broke the news on Facebook Wednesday. Alba, 29, said how her first born, Honor, is “going to be a big sister.”
“Cash and I are thrilled and wanted to share the news directly with you so you didn't hear about it somewhere else,” Alba wrote as her status on Facebook.
“I appreciated all of the love and support you all gave me during my first pregnancy and will definitely appreciate it again this time around," she added. "Have a great day! ”
Alba is married to movie producer Cash Warren. They wed in December 2007, and Honor was born in June 2008.
