Jessica Alba is set to portray the role of a mathematics genius in a new film. Three months after she welcomed her first child with husband Cash Warren, the stunning actress has signed to star in “Invisible”.

The “Fantastic Four” actress will play “a young woman who has retreated into the world and is consumed by number and math,” according to the report.

Jessica Alba won the role after “Ugly Betty” commitments forced America Ferrera to pull out.
