The reality TV show has been the hot topic of conversation recently as rumours about which big-name stars were entering the famous abode have been floating around, but fans won't have to wait too much longer to find out, as it's believed it will return to Channel 5 on August 3 - a week later than last year's explosive series.

And if the rumoured line up is anything to go by, the forthcoming instalment is bound to be explosive as, according to The Sun Online, Sarah Harding has reportedly signed up to take part, although she's riddled with nerves following some time out.

A source explained: "Sarah is fully onboard. But she is not sure if she feels ready. "

"She has been enjoying a career out of the spotlight recently and is not sure she wants to give up her low-key presence just yet."

The former Girls Aloud singer will be joined Megan McKenna's ex-boyfriend Jordan Davies as bosses want to emulate the success of the brunette beauty, who became a household name following her appearance on the show in January 2016

The insider explained to the publication: "The show turned her into reality TV gold and viewers can't get enough of anything about her - even her ex. It's why the bosses wanted Jordan - it will make for explosive television."

Helen Lederer - known for her role in 'Absolutely Fabulous' - has also been offered a mega-money deal to live in the famous house for a maximum of four weeks.

The source said: "Helen's a great addition to this year's line-up and is sure to be a big hit with fans. They offered her a big money deal that was hard to turn down and she's looking forward to going into the house later this summer."
