The two shows continue to clash on Saturday nights, even after The Voice moved the start time from 6PM to 8PM.
Last week saw both shows score ratings highs for their latest series, but The Voice closed the gap on BGT to les than a million viewers.
But Amanda reckons all the bragging from both sides is just a bit silly.
“It’s not fair on the British public, I think, to put two shows up against each other because there’s room for everybody and it just dilutes entertainment," she said this weekend.
Speaking to the Daily Express, Amanda went on: “They’re doing a good job on it (The Voice) and obviously there’s going to be a war, but not between us personally.
"It’s just a silly, entertainment ratings thing really, isn’t it? It’s a bit of pantomime, it’s not real.”
And Amanda blamed the BBC for originally pitching The Voice against BGT, despite the ITV series starting two weeks after the Beeb show.
She claimed: “I think the BBC have made the most sensible decision by moving their time slot so that people can watch both shows.
"It’s a silly thing to try and put anything up against Britain’s Got Talent, to be honest.”
Both shows continue next Saturday.
