The Style Network will begin showing the E4 reality show from its pilot episode on November 12, in what Hull admitted was a "surreal" development.
"We've also just been bought by the Style Network in the US so Made in Chelsea is going to be shown in America," she told Closer.
"It's so surreal, we couldn't have predicted this success."
In a statement, Style confidently predicted that US viewers will "fall in love" with Caggie Dunlop, Spencer Matthews, Millie Mackintosh and their Made in Chelsea co-stars.
"With a keen on eye on fashion and trends, we are confident our viewers will gravitate towards Made in Chelsea and fall in love with these fashion-obsessed, upscale, sexy twenty-somethings," said Katie Buchanan, Style's Senior Vice President, Programming and Acquisitions.
Made in Chelsea's fourth series, which features Matthews's ex and a "spoiled" and "opinionated" fashion student among its new additions, airs in the UK this autumn on E4.
