Jessica Alba is one hot mama!

The 31-year-old stripped down to an itsy-bitsy bikini on Wednesday, while vacationing with her family in Amalfi, Italy. The mother of two showed off her killer post-baby body -- she gave birth just 11 months ago -- while playing in the pool with daughter Honor, 4, and baby Haven.

"Excited to be here," Alba tweeted Wednesday morning, along with an adorable family snapshot.
