In the most telling part of the Q&A, when asked if she missed season winner Hamish Boyt, Lexie shook her head firmly: "Nope," she revealed.
Since the couple announced their split, sources close to the pair have admitted things may have turned sour for the once happy couple.
Boyt has since left the country and took to Instagram to share a picture of himself departing Auckland airport. He has since posted pictures from a beach on the Gold Coast.
The revelations follow Brown's announcement of her split from Boyt the day the After The Final Rose special aired. The couple appeared happy together in the televised reunion special and had confirmed to the nation they were still together.
But the romance was soon over. She posted on her Instagram stories the morning after the special aired and announced to her followers they were no longer together.
"Ok so. It has been a wild ride since day one on set and I have loved every minute.
"But as of last week, shortly after filming the reunion I have reverted back to being Miss single Lexie Brown.
"The support throughout the show and since it finished has been mind-blowing.
"I cannot thank everyone enough. I feel so loved and I love you all."
The show concluded in March, and the couple embarked on their relationship shortly after the show ended. Brown had to choose between Boyt and Australian bachelor Todd Dialectos.
Boyt has still not publicly addressed the split, and the former couple refused media interviews after the announcement they were no longer together. The travel photographer has recently moved to Australia, according to posts on his Instagram account.
In an interview with the Herald when the couple were still together, Brown alluded to the potential challenges of taking the relationship off-screen.
"It's a quite speedy time of growth in a situation like ours. You come off the show and you don't really know each other," she said the morning after the finale screened.
"You hear stories, and you can understand how people break up the day after the final rose ceremony because you really don't know people. I reckon the first 24 hours can be really confronting possibly, depending on who you pick."
