The 20-year-old Jersey farm girl and the teacher-turned-porn actor were nominated by the rest of the group for the third public vote.
As with last week, the result was announced on the official Big Brother Twitter feed via a post with links to both Lauren and Benedict's pictures.
Benedict, who was barred from nominating as part of a task yesterday (June 17), earlier angered a number of his housemates by admitting to masturbating in the shower.
Meanwhile, Lauren claimed earlier this week that she wants to leave the Big Brother compound.
One of the nominees will become the third housemate evicted from this year's series on Friday, following Chris James and Victoria Eisermann.
