A premature birth has held up production on Reese Witherspoon and Jack Nicholson's new movie.
The two stars are currently working on baseball picture How Do You Know but the shoot has been halted after Kathryn Hahn, who plays a pregnant secretary, went into labour during filming on Saturday (25Jul09).
The actress, who was not due to give birth until September (09), welcomed baby Mae on Monday (27Jul09).
Producers are now reportedly considering hiring another actress to reshoot all of Hahn's scenes in a bid to keep the movie on schedule, according to RadarOnline.com.
