The new Timebomb theme for Big Brother 2015 will see the housemates get really 'messed with' with a big twist tonight.
Host Emma Willis reckons that Big Brother Timebomb, which begins this evening, will provide drama... and hopefully some fun too!
She said: "The theme this year is Timebomb which basically means we've got a really good excuse to mess with them in any possible way."
Emma, who is back alongside Rylan Clark for this year's sixteenth run, continued: "We can freeze time, rewind time, and they can live in different times... in my head that's what I'd like to happen."
The main show presenter went on to say that she was looking forward to seeing a bit of a fun series this time around compared to the show's more recent outings.
"I think for the past few series we've had a lot of drama," Emma said. "Yes, we want to see genuine interactions with people that may create drama but I think it's also good to see fun."
Emma has also revealed that tonight's launch show will see a twist that's 'never been done before'.
"We've got a twist at the end of tonight's show and it's something we've never done before, it's another Big Brother first," she teased.
Emma added: "There's fifteen housemates going in and I think it's going to be a cracking series, watch this space!"
Big Brother: Timebomb kicks off TONIGHT at 9PM, May 12 on Channel 5.
