Last year saw many hits back and forth from the talent of both shows, with Reggie claiming the Voice was more "credible" and Danny O'Donoghue claiming to have only watched "10 minutes" of the rival series.
But ITV bosses hit back, blasting the series as a "derivative" of their own shows such as Britain's Got Talent.
Reigniting the yearly war of words in the press, Reggie said today: "The rows between the judges on X Factor aren’t real.
“The Voice is real – you can never tell what is going to happen.
“If our judges fall out in the new series it will be real.”
This year's second series of The Voice UK will see Jessie J, Will.i.am, Sir Tom Jones and Danny O'Donoghue all back on the panel, and Reggie thinks it was a good decision to keep the same coaches.
He said: “That’s the one thing that’s constant on our show – they always act the way that they feel. They don’t do anything because anyone has prodded them.”
Speaking to The Daily Star Sunday, Reggie added: “The talent this year is bloody good – it’s really looking great. So it’s exciting to be working on this series.
“The changes they have made are definitely making the show that bit more juicy.”
The Voice UK is reported to start on March 30 with the first round of blind auditions.
