London, Aug 3 (IANS): Actress Jessica Alba, who is expecting her second child, says her multi-tasking skills impressed director Robert Rodriguez so much that he created a role for her in the next instalment of "Spy Kids".

This is not her first film with Rodriguez - she had teamed up with him for action movie "Machete".

"When I was shooting 'Machete', him seeing me trying to change my kid's diaper and take conference calls and I'm on the set trying to learn lines and trying to do a million things at once, kind of inspired him to write the character that I play - a woman who's trying to do a million things at once," contactmusic.com quoted Alba as saying.

The actress has a daughter Honor with husband Cash Warren and now they are expecting their second child, which is due next month.

The singer says even Rodriguez is good at handling various responsibilities.

"When I became a mother (first time), I talked to him (Rodriguez) about getting back to work and how does he do it - how does he juggle spending time with his family (and his five children) but also focus on his career because he's done it so well," she said.
