Kate Middleton is doing her first television interview since becoming a royal.
To help celebrate Queen Elizabeth's 90th birthday, the Duchess of Cambridge, along with other members of the royal family, has participated in a film on "her life and reign."
"We've been fortunate to have the participation of so many members of the royal family to mark this historic milestone in the life of the Queen," Nick Kent, executive producer for Oxford Film and Television, said of the two-hour film. "It's a remarkable story of an extraordinary life, which in so many ways reflects the changing face of the nation."
The working title for the movie is The Queen At Ninety and will also feature commentary from Prince William as well as Prince Charles and Camilla, Duchess of Cornwall.
The ITV broadcast will be hosted by Ant and Dec and is expected to air in May.
