The reason why Spencer Matthews isn’t able to support Vogue Williams in Australia

Vogue is set to be one of this year's late arrivals

However, her husband, Spencer Matthews, will be unable to travel to Australia to support Vogue due to timing issues.

Matthews is embarking on his own mission to complete seven full Ironman marathons on seven continents in 21 days.

The 37-year-old is currently on his way to South Africa for his next race, so due to conflicting schedules, he'll have to cheer Vogue on from further away than initially hoped.

An insider told the Daily Mail: "The timing isn’t ideal at all, but sometimes these things happen, and Vogue and Spencer’s diaries just clash.

"Of course, Spencer would want nothing more than to support Vogue in Australia and be there waiting for her when she leaves the jungle, but both are committed to their own projects, and unfortunately, the schedules overlap."

The source went on to add that the couple's three children will also remain in London.

They continued: "There’s a small chance Spencer could finish his triathlon challenge ahead of schedule, but it’s unlikely he would then fly to Australia.

"They’ll both be missing their children, who will stay in London, continue attending school, and no doubt support their parents from afar – catching Vogue on TV whenever they can."

Vogue wasn't among the batch of celebrities that kicked off the return of the beloved series on Sunday, however, rumour has it she will make her arrival soon.

Spencer added fuel to the rumours by acknowledging that he was unsure if Vogue would be able to support him on his own adventure while speaking on Good Morning Britain last week.

Presenter Susanna Reid asked the former Made In Chelsea star: "Is Vogue going to be able to be there to support you, or is she going Down Under on her own epic mission in I’m A Celebrity?"

Spencer cheekily replied: "I mean, the announcement was made yesterday, was it not?"

Susanna was quick to point out: "But there’s some late arrivals, we hear."

Spencer then coyly said: "Listen, you know more than me as ITV. But she, no, she will be there on Thursday supporting me and, she hopes to be at the finish line."
