Fedotowsky and Martinez got engaged on the ABC dating show in 2010 but announced in November 2011 that they had decided to end their relationship.
However, recent rumors suggested that the duo had reconciled at the wedding of fellow Bachelorette stars Ashley Hebert and JP Rosenbaum earlier this month.
Fedotowsky has now played down the speculation, telling Life & Style: "It was so great to see him, honestly.
"I feel like we are just good friends now. We spent a lot of time together at the wedding and it was a good time."
Fedotowsky also described Hebert and Rosenbaum's wedding as "beautiful", saying: "Their vows brought me to tears. I was blown away by her dress. It was so stunning. Everyone had such a good time."
Earlier this year, Fedotowsky admitted that she does not expect to return to The Bachelorette in the future.
