Music mogul and judge Simon joked he was dying to evict Big Brother from the schedule.
He told the Daily Star: "It's our moral duty to drive Big Brother off our screens."
He continued: "I think viewers prefer to watch variety acts such as nervous knife throwers rather than eight people sitting in a room."
Britain's Got Talent, which also stars judges Piers Morgan and Amanda Holden, kicks off on April 11 and there will be seven audition shows on consecutive Saturdays before a week of nightly shows so fans can pick two finalists who will battle it out on May 30.
But while it is claimed the start of this year's series of Big Brother has been put back until June so as not to clash with Britain's Got Talent, a Channel 4 spokesperson said they had not yet confirmed a date.
"We never confirm scheduling this far in advance and haven't confirmed a start date for Big Brother yet," she said.
