Actress Laura Vandervoort has joined the growing cast of Ted for Universal Pictures and writer-director Seth MacFarlane.

The story centers on John (Mark Wahlberg), a grown man who made a wish as a child for his teddy bear to come to life, which it did. Now the teddy bear, which will be voiced by Seth MacFarlane, still lives with John and has become a foul-mouthed bad influence on the man. Laura Vandervoort will portray a gorgeous co-worker of John's, who doesn't quite register the fact that nearly every man she meets drools over her.

It isn't clear when production will start on Ted at this time.
