Oksana Grigorieva Receiving Threats

Mel Gibson's ex-girlfriend Oksana Grigorieva has turned to Los Angeles police for help after receiving a number of threatening phone calls on Tuesday (13Jul10).
 
The Russian singer was subjected to multiple menacing calls, including one that "could be interpreted as a death threat", according to TMZ.com.
 
Sources claim Grigorieva, the mother of Gibson's baby daughter Lucia, was "scared to death" by the voice messages and reported the calls to authorities.
 
The threatening phone calls were reportedly made by people angry at Grigorieva for accusing the movie star of striking her during their relationship.
 
The couple split earlier this year (10) and Gibson is currently at the center of an LAPD domestic violence investigation.
 
He has denied hitting Grigorieva.
