In a short preview clip of the show released by the Oprah Winfrey Network, the TV show host can be seen telling the couple blankly, that they had been accused of cheating by the New York Post.
Insiders had exclusively told the publication back in May that the singer had cheated on his model fiancée by kissing another woman at a Manhattan restaurant.
Teigen had denied the rumours vehemently on Twitter, after the news broke. The pair, who has been dating for seven years and engaged since 2011, has moved past the scandal and set a date for the nuptials. The video also shows Oprah questioning their long engagement.
