Duchess of Cambridge visits the set of 'Downton Abbey'

LONDON, March 12 (UPI) -- The duchess of Cambridge visited the set of "Downton Abbey" Wednesday, bringing some real royalty to the show with television's favorite aristocratic family.

Wearing an ivory coat from the maternity line JoJo Maman Bebe, she greeted cast and crew on the set and even visited hair and makeup before sitting in on filming.

"You've come just at the right time, Phyllis [Logan] is about to have her Botox put in," joked Robert James Collier, who plays the devious under-butler Thomas.

The tour was after Catherine visited an art gallery in Margate, where she had a laugh with locals when she admitted, "I sometimes forget I'm pregnant."

She is eight months pregnant with her second child. Her and husband William's first son, Prince George, is 19 months old.
