For the first time in the football competition's history, the final will air on a weekend. ITV1 has the rights to the sporting event, which features Jose Mourinho's Inter Milan taking on Bayern Munich.
The final takes place in Spain on Saturday, May 22, meaning that Simon Cowell's Got Talent will be pushed back a day to ensure that it gets a primetime slot.
"We can't squeeze BGT on before, especially as football fans will want to hear Jose's mind games in the build up to the match between Inter Milan and Bayern Munich," a source told The Mirror.
Britain's Got Talent continues tomorrow night at 8pm on ITV1.
