Pregnant Jessica Alba on Choosing Baby Names

Jessica Alba is expecting her second child with husband Cash Warren later this year and the actress revealed her proves for choosing names.

"I think every parent writes names down or thinks of names knowing that your kid's going to be stuck with that name for the rest of their life," Jessica said with a giggle. "But I haven't decided on a name yet."

In theaters August 19, 'Spy Kids: All the Time in the World in 4D' finds Jessica as Marissa Cortez Wilson, a retired secret agent raising a new baby and struggling to win over her twin step kids, Rebecca (Rowan Blanchard) and Cecil (Mason Cook), with hubby Wilbur (Joel McHale).

"You're just going to have to suspend your disbelief that someone like her would be with me," said Joel, who joked that he prepped for their kissing scenes by soaking his lips in bleach.

Jeremy Piven plays a bad guy in the movie and he dished about the film's special 4D quality, allowing the audience to smell what's happening in the movie.

"There are a lot of smells that are going to be amazing," said the "Entourage" star. "And then there's going to be some smells that are like, 'For the love of God, I may not want to smell that.'"
