With Big Brother 2015 getting set to explode onto our screens with a new 'Timebomb' theme, here's a look at what we know about the new series.
That Timebomb theme
This year's Big Brother's tagline is 'Timebomb', although it's not precisely clear what this will involve.
There are rumours of past housemates returning but Big Brother has only teased: "The Housemates’ past, present and future will be in the hands of Big Brother."
Show bosses explained: "From the moment the new Housemates walk through those doors they’ll enter the world of Big Brother: Timebomb.
"With Big Brother playing with the concept of time, the tasks, secret missions and twists promise to have tension, drama and intrigue. How will this affect the housemates? Time may be a friend or an enemy and for some it may well run out…"
Emma Willis and Rylan Clark are back as hosts
After a sudden departure from Bit On The Side and rumours of a move to The X Factor, it's fully confirmed that Emma is very much sticking with Big Brother and is back to front this summer's series.
Meanwhile, Big Brother’s Bit On the Side returns with Rylan Clark and a mix of celebrity panellists and an audience of BB fans to debate hot topics, reveal exclusives and go behind the scenes of the main show.
The Big Brother start date
And viewers in Ireland can tune in for the first time since the move to Channel 5 by watching on TV3.
A tiny bit about the house
There are no house pictures yet but we do know that the BB House has been totally revamped and is decorated in a sophisticated, sleek ‘Mad Men’ 60s style. The Diary Room is said to be back downstairs with a new layout inside.
Finally, Channel 5 have unveiled the official artwork for this year's Big Brother eye, above.
