Callum Knell, Jack and Joe Glenny, Hazel O'Sullivan and (once again) Dexter Koh have been picked by their fellow housemates and will go head-to-head in the public vote.
The results were revealed via a surprise cruel twist from Big Brother, which involved the private nominations being screened in front of everybody.
Callum picked up the most nominations this week, collecting five votes.
However, Callum appears to be safe in the early betting with relatively long odds of 11/1.
Glamour model Hazel is the hot favourite for the axe with odds of 2/7. However, the twins aren't safe and can be backed at 5/2. Dexter is the longshot and looks likely to survive again with odds as large as 33/1 on him leaving.
Gina Rio remains the firm bookies' tip to win the series with odds now as short as 8/13 on her triumphing.
Big Brother airs every evening on Channel 5. Emma Willis will be interviewing the latest eliminated housemate on Friday's (August 2) live show.
