Pippa Middleton and James Matthews' relationship was the topic during Spencer Matthews' appearance on 'This Morning'

The world is in high anticipation of Pippa Middleton’s upcoming wedding to hedge fund manager James Matthews, and no insider is safe from the prying ears and watchful eyes of the media. Spencer Matthews, James’ brother, was placed on the hot seat after an interview with Phillip Schofield was steered towards the imminent nuptials.

Spencer looked flushed when Philip asked some questions about the relationship James has with Pippa during his appearance on This Morning. Spencer, who went on the show to talk about the Michael Matthews Foundation -- in memory of their late brother -- revealed that James prefered to keep his private life private. Despite the planned talking points, Phillip was keen on continuing the conversation about the engaged couple.

The host asked Spencer if James had climbed the Matterhorn mountain. “You know where I’m going with this,” he said. “When James climbed the Matterhorn, did he take Pippa up the Matterhorn?”

Spencer, who was clearly flustered, stuttered out his awkward reply. “I believe he must have done,” he said. “I supposed we all support the foundation in the same way.”

The Michael Matthews Foundation, as Spencer revealed, is very close to his heart and was put up shortly after the death of Michael when he was just 22 years old. “The foundation was made to help provide children in remote areas with education,” he explained. “My brother passed away 18 years ago, and the foundation was set up afterwards because we wanted the name to live on in a nice way.”

Michael became the youngest Briton to climb the summit of Mount Everest. He died from complications on his way down the mountain.
