The Monster's Ball actress suffered the injury while filming sci-fi film Cloud Atlas in Spain.
She was later pictured leaving hospital in a wheelchair with her leg in a cast.
While Cloud Atlas distributor Warner Bros only confirmed that Berry broke her foot while "walking" in Mallorca, an insider has now claimed that the mishap occurred during an encounter with a wild animal.
According to People, Berry gave chase after her 3-year-old daughter Nahla started pursuing a goat over some difficult, rocky terrain near their villa.
The source says that it is when she made her way back with Nahla that she slipped and fell.
Filming on Cloud Atlas, which also stars Tom Hanks and Hugh Grant, has continued despite Berry's injury.
