Julia Roberts has completed her first acting job since giving birth to twins nine months ago, a music video for rocker Dave Matthews.

Roberts plays a woman followed by a shadowing man played by Matthews in the promo for DREAM GIRL.

She agreed to star for free - provided she was allowed breaks to nurse babies PHINNAEUS and HAZEL.

The video was shot in Harlem, New York, and at the city's Brooklyn Botanical Gardens, and will be released later this year (05).
