Up next in the Hollywood Baby Train is Jessica Alba!

Jessica Alba is pregnant. The actress announced on Facebook that she and husband Cash Warren are expecting their second child together.

The 29-year-old actress wrote, "It's been a while since I've been on FB & I thought I'd drop by to let you all in on some exciting news: 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. 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. Have a great day! Jess."

* Cash added on Twitter, "@jessicaalba are beyond excited about the news! Honor is going to be a great big sister. Thank you all for the wonderful messages!!"

* Alba and Warren tied the knot in May of 2008 -- just a month before Honor was born.
