Celebrity SAS Who Dares Wins signs up Geordie Shore legend alongside Towie star as cast fly out to New Zealand

CELEBRITY SAS Who Dares Wins' latest recruit is a reality TV star determined to prove "she's changed."

The Sun can exclusively reveal Geordie Shore star Marnie Simpson, 31, has already jetted away for filming for the gritty Channel 4 show.

She joins the likes of TOWIE's Bobby Norris, 36 - who we revealed had also signed up.

Marnie, who recently married partner Casey Johnson, is battling it out to make her two ";kids proud."

A source told us: "Marnie is on her way to New Zealand as we speak - determined to prove how much she's changed compared to the party girl from Geordie Shore.

"She wants to make her kids proud and when they are older and there's no tougher show on TV.

"It's something she can play to them to show how strong their mum was."

The Sun has contacted reps for Marnie and the show.

She has revealed no signs of the show on her social media pages - instead recently posing in a tight white bodysuit.

Marnie also recently gave a glimpse of her derriere as she stripped to a thong.

We recently told how show bosses are in the midst of scrambling to find replacements to star in the latest Celeb SAS series.

An insider told The Sun: "It's been huge behind the scenes headaches for bosses after a string of celebs pulled out at the last minute.

“The stars fly out next week to go into quarantine for five days ahead of filming beginning in early July, but in the last couple of weeks bosses have had to scramble to replace several famous faces who couldn’t go ahead.

“It created a frenzy behind the scenes as they thought they had the cast locked and it meant they had to find replacements really quickly.

“It’s been really down to the wire, but they’ve managed to find some great celebs who could step in and were up for the challenge and they’re confident they’ve got another great cast."

Sources added that the reasons behind the pull-outs raged from stars not being fit enough to take part, to celebs being offered other jobs - creating a schedule clash.

The Sun previously told how Bianca Gascoigne will be taking part in the next series.

In last year’s show, which was filmed in Thailand, contestants Matt Hancock and James Argent struggled with trench foot, a condition caused by prolonged cold and damp — and in the new series the celebrities will be battling freezing cold conditions, as it is currently winter in New Zealand.

The series with Matt and Arg will air later this year.
