0531_alba_singleJessica Alba is back in black -- and looking good.

The actress dons a slinky jumpsuit -- reminiscent of the one she wore in her "Dark Angel" days -- in her new movie "Spy Kids 4: All the Time in the World."

In the fourth installment of the popular action-adventure family film, Alba plays Marissa Coretz Wilson, a homemaker with a secret agent past.

When the villainous "Timekeeper" (Jeremy Piven) threatens the world, Wilson is called back into action, and back into her spy suit.

Former Spy Kids Carmen (Alexa Vega) and Juni Coretz (Daryl Sabara) return to lend a hand, too. Newcomers Rowan Blanchard and Mason Cook play the new "kids."

Check out the action-packed thriller below:

Don't expect Alba to slip into any skintight suits in real life any time soon. The actress is expecting her second child with husband Cash Warren.

"Spy Kids 4" comes out in theaters on August 19, 2011. For even more coverage of all of the summer's hottest movies, be sure to check out our Summer Movie Guide here.
