They're both model foodies and now it seems as though Rozanna Purcell is hot on the heels of Rosanna Davison in the cookbook stakes as the brunette has finished writing her recipe book.
The former Miss Universe Ireland contestant (24) has been busy in recent months, turning her recipe collection from her Natural Born Feeder blog into a cookbook for publishers Gill & Macmillan.
While Roz is keeping quiet on when her debut food bible is set for release, her musician boyfriend Bressie let the cat out of the bag and hinted that it could be hitting the shelves sooner rather than later.
The Voice of Ireland coach praised his model-turned-food entrepreneur other half over Twitter, revealing she had completed her cookbook.
"So @RozannaPurcell just finished writing her #naturalbornfeeder book and it's pretty damn impressive," the former Blizzards frontman said.
Last week former Miss World Rosanna said that the release date for her book, Eat Yourself Beautiful, had been brought forward from Christmas to September.
Rosanna previously said she isn't worried about competition from other models when it comes to healthy eating recipes.
"What's important to me is having my nutrition qualification, because it's very easy to bandy about the idea of healthy eating and I would find it very difficult to take advice from somebody who's not qualified in the area," the striking blonde said.
"So there's nobody else out there that has my qualification and also has a world title in the beauty area, and can combine them both."
Tipperary girl Roz recently told the Diary that tasting recipes for her blog has meant that she has had to work out more than ever.
"People always ask how I cook so much and keep trim but I train all the time and I have to do a lot more of it now because I always make sure to test everything myself," she said.
"I would never put up a recipe on my website without tasting it myself, that's such an important part of cooking for me.
"Other people say that they make things and they have tasters who come to try the dishes so that they don't have to eat it, but I could never do that," she added.
