Kate Middleton couldn't be happier to be a mom-of-two!
In a new documentary honoring Queen Elizabeth's upcoming 90th birthday, the Duchess of Cambridge, 34, candidly opened up about her children, Prince George, 2, and Princess Charlotte, 10 months — and revealed she and husband Prince William are thrilled to have a daughter!

"It's very special having a new little girl [in the family]... I feel very, very lucky that George has got a little sister," she said in the documentary, which airs in the UK on Sunday, March 27 on ITV. "The Queen was really thrilled that [we had] a little girl, and I think as soon as we came back here to Kensington [Palace] she was one of our first visitors here."
During Kate's interview — her first official sit-down since dishing on her royal engagement to William, 33, in November 2010 — she also revealed the special name her adorable son, George, calls his great-grandmother, Queen Elizabeth.

"George is only 2 ½ and he calls her 'Gan-Gan,'" Kate said, "She always leaves a little gift or something in their room when we go and stay [with her], and that just shows her love for her family."
Kate and William — who married in April 2011 — welcomed George in July 2013 and Charlotte in May 2015.
