The Herald can reveal how the sky's the limit for the 5'11" stunner, who finished seventh in the international pageant in Las Vegas.
Trump co-owns the Miss Universe franchise and was present during the contest.
Agents for his modelling agency swooped on Rozanna shortly after the competition ended. She now has a once-in-a-lifetime opportunity to carve out a name for herself in the States after being offered the contract.
Her mentor Andrea Roche said she couldn't be more proud of her fellow Tipperary native -- and she has now been inundated with offers of lucrative modelling jobs, both in America and South America.
"It was an amazing night and she has now been offered contracts in Mexico as well as Colombia," said Andrea.
Rozanna was listed as one of the hot favourites ahead of the contest and has sparked claims among her loyal pals that she was "robbed" of the Miss Universe title.
She was flown over to Colombia for two weeks of special mentoring from pageant expert Miguel Martinez, with her poise and good looks making her a popular choice.
Gorgeous Rozanna will now have to decide whether to come back home for her modelling career, or try to make it internationally.
And her namesake Rosanna Davison has urged her not to take the competition results to heart. "Roz...many will conclude that you were robbed, but that's the nature of international beauty pageants -- there will always be complaints and questioning of scores," she continued.
Andrea Roche said Rozanna had "something magical and special about her" and has a "big future".
