The Four Weddings and a Funeral star spotted vile messages aimed at her on the social networking website, including death threats and a sinister boast about a voodoo doll.

The hate-filled tweets were so vicious that MACDowell vowed to reduce her online presence and spend much less time on the microblogging site.
