The First Lady, who agreed to the interview with the USA news channel with no pre-conditions about what could be asked, added that speculation that her marriage is not a good one is "media gossip".
Asked why Giuliani would say that, she said: "I don't know". The First Lady of the United States brushed off Donald's alleged unfaithfulness while conducing her first sit-down interview with ABC News' Tom Llamas.
Despite President Trump's personal attorney Rudy Giuliani's assertion that Melania Trump "believes in her husband, she knows it's not true", Melania disclosed that she never had a conversation with Giuliani about where she stood.
When asked if the rumours had hurt her, she paused.
And that's all she wore folks - the first lady spent the rest of the week laying low, likely resting up after her big trip.
She said: 'Media what is speculating, yeah. That one was too easy: "I don't know; you have to ask him", the First Lady replied. However, she went ahead and detailed her 2006 alleged affair with Donald Trump in a CBS "60 Minutes" interview in March. It's not always pleasant of course.
The 48-year-old dismissed the suggestion that repeated rumours of her husband's affairs had put a strain on their 13-year marriage.
During the same episode, Llamas wanted to make something clear.
'It's what media speculate, and its gossip. The two were married in 2005 (the same year of the now infamous Access Hollywood tape where the then-Celebrity Apprentice star said he could grab women by the genitals because he was a star.) In addition to Stormy's claims, Playboy model Karen McDougal claims she and Donald had an affair, as well.
"I know people like to speculate, and speculate about our marriage".
Later Friday, the first lady's spokesperson Stephanie Grisham fired back the show and Brown.
After living in the White House for almost two years in the shadow of one of the most controversial and scandal-tarred presidents of modern times, she appeared confident but also controlled, keeping her answers to hard questions short.
