Speaking to her friends Kyle Sandilands and Jackie Henderson on their KIIS FM radio show, Monk confirmed the man who has won her heart.
Luckily for fans, the radio show beeped out the names to not ruin the series.
"Are you sure that's the right decision?" Sandilands asked.
Monk, 37, responded: "I get a good vibe off him."
When Henderson asked how often Monk and the winning man speak on the phone, she said it was three times a day.
Monk is currently in Thailand with her best friend so she doesn't accidentally spoil the ending of the show by trying to see her boyfriend.
The Bachelorette star also revealed that the audience will be 'surprised' when they eventually find out who the winner is.
It has been speculated that Stu Laundy is the man who wins The Bachelorette and Monk's heart.
