We don't know much about the world of celebrity impersonators, but we imagine that keeping up with the celebrity's changing look is key. If the star gets a haircut, you get one too. If the star gets a serious spray tan, you hit that salon. If the star gets pregnant, well, strap on the fake baby bump.
Agan has been impersonating the Duchess of Cambridge professionally since May 2012, when customers at the Northamptonshire restaurant she worked at kept telling her she looked like Kate. The 32-year-old quit her waitressing job and devoted herself full-time to being Kate, sporting the bouncy hair and the duchess' most iconic outfits. Agan hit the big time when she was invited on "Good Morning America," appearing on the show in Kate's famous navy Issa dress and an engagement ring.
Now she's adjusting her style to match the pregnant royal's. On March 5, Heidi posted on her Facebook, "Picked up my "baby bump" today. How strange :)" She also posed for a spread in the Daily Mail depicting her at all stages of Kate's pregnancy (with chic maternity wear to match, natch).
"It's difficult at the moment as she's not big enough yet to change her entire wardrobe so it's difficult to see how she's going to dress it," Agan told the BBC. But she sure is doing a good job guessing.
