Big Brother bosses have responded to claims from viewers that they've been unable to evict certain housemates.
Some Twitter users have posted online that they've not been able to register their votes ahead of tonight's latest live eviction.
A statement now posted on the official Channel 5 Big Brother website says in response: "We've seen some Tweets around housemate votelines not working as they should.
"We take any queries of this nature very seriously and look into them with the help of BT and appropriate mobile networks.
"To assure you, votelines are tested across landline and all mobile networks every day, and all votes are scrutinised and independently verified by our third party auditor."
Four housemates face the boot in tonight's show with the one who gets the most votes leaving straight away.
Back in Tuesday's show we saw the latest round of nominations as Andy West, Jayne Connery, Georgina Leigh Cantwell and Evelyn Ellis all ended up facing the public vote this week.
Over the past 24 hours the odds on Georgina going have dropped, going from 1/3 to 1/9 while Evelyn appears to look safer at odds of 8/1 to go.
In our poll more than 50% of voters have backed Georgina to leave, twice as many as who want Evelyn gone.
Big Brother airs from 9PM tonight on Channel 5.
