Kate Middleton Impersonator [PHOTOS]: Heidi Agan Buys Baby Bump 'Made in Various Sizes,' Duchess Lookalike 'Becomes Pregnant'

32-year-old Heidi Agan used to make her living as a waitress but has since moved on to royal impersonator, making appearances as the Duchess of Cambridge, Kate Middleton. Since Kate Middleton is over 5 months pregnant, Agan has made a purchase to accommodate the royal pregnancy: her own baby bump "made in different sizes." So now as the 31-year-old royal's bump grows up until the July due date, Agan is prepared for all of the different changes in size for her appearances.

"As Kate grows I will too - to be authentic I thought it was important," she said. "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."

The mother of two living in Colby, Northamptonshire, quit her waitressing gig after countless customers told her she resembled the Duchess. She is now a royal doppelganger, traveling around the world for appearances.

"To have done 12 years of something you know and then to leap into an industry that gives with one hand and takes with another is difficult, but I'm just really happy and feel blessed that I did," Heidi Agan said. "You just have to pinch yourself as I can't believe it's happened. My daughter argues over which pictures of Kate are me." 

In order to keep up with her royal impersonation subject, Agan stays up to date on social media and news of Kate in order to match outfits and looks.

Agan said, "The most expensive shoes I've bought as Kate were about £200, the dress was about £300 - which I don't think is that bad considering her original evening wedding dress by Alexander McQueen would have cost ten of thousands of pounds. I have to get the clothes, the mannerisms, the way she stands and interacts with William right. Things like that are all very important if I want to be the best."

Heidi says that her children, 11 and 4 years old, are very proud of their mother.

"It's just been incredible and I feel so blessed with it and without the support of my family I just couldn't do it," she said. "Appearing as Kate has given me the opportunity to spend more time with my own children than if I was doing my waitressing job and that's priceless."
