Jessica Alba
is back in a bikini -- just four months after giving birth to her second child!

The sexy actress showed off her slim figure Wednesday in a two-piece bikini while vacationing with husband Cash Warren and kids Honor and Haven in Los Cabos, Mexico.

Alba gave birth to the couple's second daughter Haven back in August.

Her man, Cash, was looking pretty good sans shirt too. Talk about a fit family!

Check out more photos from their day by the pool above.
