The Duchess of Cambridge’s sister Pippa Middleton is set to join NBC’s Today show as a correspondent, it has been reported.

According to the New York Post’s Page Six site, Pippa, who had her first ever television interview on the show in June this year, is currently taking part in a test shoot in Utah.

The 31-year-old party planner is expected to become a regular correspondent for the US show, reporting on subjects including lifestyle and health.

Pippa recently used her Waitrose column to reveal an insight into her own lifestyle by sharing her fitness regime.

Pippa also talked about her nephew Prince George, describing him as ‘a very dear boy’, and discussed her new-found fame after the 2011 Royal Wedding.
