Kate Middleton Look-Alike Buys Fake Baby Bump While Real Pregnant Royal Shops for Veggies

Heidi Agan shows off her fake growing belly as she tries to keep her royal look authentic

Now, this is showing dedication to your craft. 

Former waitress Heidi Agan quit her job serving tables to become a Kate Middleton impersonator after numerous people told her she resembled the royal.

Of course, Agan's new line of work requires her to maintain a certain look—which, nowadays, means going out and buying a fake baby bump "in various sizes."

"As Kate grows I will too—to be authentic I thought it was important," the 32-year-old single mother of two told the BBC. "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 posted on Facebook earlier this month, "Picked up my 'baby bump' today. How strange :)," and even posed in a variety of Duchess-reminiscent outfits with said bump for the Daily Mail.

"Today has been a wonderful day full of amazing blessings. I am so, so lucky. To all who are supporting me, thank you!! Love Heidi," she tweeted today.

Meanwhile, the real Kate Middleton was spotted grocery shopping today in an Anglesey supermarket.

A source tells E! News that the mom-to-be, who appeared to be rocking a bare face, was "near the entrance right by the fruit and vegetables aisle" picking out groceries, her bodyguard nearby.
