Big Brother Timebomb 2015 Live Stream Online Video: Watch UK Launch Of Reality Show Hosted By Emma Willis!

"Big Brother UK" is back for another hot summer season full of secrets and lies. The twist this year is the "timebomb" that will cause havoc in the house. Hosting the live launch and main show is the lovely Emma Willis. She will meet all the new housemates that will forego their summer plans to take a holiday in a studio full of bright lights and cameras watching your every move for the public's enjoyment. The compound at Elstree and Borehamwood has received a face life and will be open for a new set of housemates that will create drama, get drunk and party all day long. Willis shared a photo on Twitter that showed what the new Diary Room chair will look like. See it down below and tell us what you think.

Rylan is back as host of spin-off show "Big Brother: Bit On The Side" and is thrilled to be fronting the show all by himself this season. "Emma has done the show for years and she has built such a good baby for me to look after. 'BBBOTS' is such a good show, and if there was a spinoff show category at the Television Awards, I know we would be up there," Digital Spy reported. "I love the show so much, and I will always put the show first. This is my seventh series, so I know what works and what doesn't. Four years ago, that would have been me sitting in that audience. I totally get it!"

What does the "timebomb" have to do with this year's show? "I would like to see them have to live in the future or go back to their past, or live in medieval times. I don't know exactly what they are going to do but I'm a real fan of 'Back To The Future' - so I'm hoping it has a lot to do with time travel," Emma told Digital Spy. The show will air Tuesday, May 12 at 9pm GMT on Channel 5 in the UK for a two-hour launch. It will be live streamed on the Channel 5 app on the iOS App Store as well as the official website. Following the main show at 11pm is "BBBOTS" and a live feed starting at midnight.
